Initial effects on sleep
During the initial side effect phase of helminthic therapy, some self-treaters may experience insomnia or hypersomnia - especially if they have taken larger doses - while others report improved sleep.
Insomnia has been noted by an HDC user.
I took my second dose of HDC
8 days ago and have been suffering from insomnia. Nothing too bad just waking up 1.5 hours earlier than normal every day which is very unlike me. I took 30 the first time but this time took 50 just to see how I tolerated a higher dose. I have also had nasal congestion. 
And by several users of NA.
This is day six since my inoculation
and for the past two days I've felt a little hyperactive and have had pretty bad insomnia. Although I am prone to these problems anyway, it's pretty unusual for it to happen a couple of days in a row like this… I notice one other poster mentioning a deterioration in sleep quality after about 10 days. 
For the past two weeks (after inoculating with 5 NA
) I've barely slept. Some nights I'm getting as little as three hours and then I'm still awake the next night even though I feel tired. 
I inoculated with 5 NA close to 3 weeks ago and I've suffered from insomnia for the last 5 days or so. This is highly abnormal for me as I usually fall asleep in less than 1 minute. Sometimes I fall asleep in less than 10 seconds according to friends. (I might have narcolepsy, haven't been tested) Now it takes me 3-4 hours to fall asleep every night and I still wake up 5-10 times after that. I haven't had insomnia in over 10 years.
I've never had an issue falling asleep or falling back asleep, but now (7 weeks after inoculating with NA
) odds are much higher I'll have a tough time falling back asleep if I awake. Also, I'm a life long nap taker, and always for 15-20 min. However now I tend to wake up after 12 min or so - I almost never sleep to my alarm. And also I still tend to feel sleepy during the day. 
Occasionally, a degree of insomnia may persist.
I used to be able to sleep like a rock and nap too but it's a bit more variable now (at 14 months post inoculation
). Sometimes awake long periods in the night, sometimes sleep well. Napping is hit and miss. 
A few self-treaters have experienced hypersomnia.
I took my 6th dose of HDC
. Now, I am in my 11th week of taking those. The only side effect that I have really felt consistently throughout the entire journey thus far is sleepiness. I would not call it fatigue because I am not exhausted at all. There are moments when I just have to fall asleep. This is a huge shift from my sleep deprived past. I would never sleep more than 4-5 hours per day in the past 10-12 years. Now, it is like ‘hey, I know you just slept 10 hours last night, but how about a 2 hour nap? 
5 days post inoculation
(with 35 NA
) and I have excessive sleep. I sleep my usual 9 hours, get up for 2 or 3 hours of feeling woozy and then get so tired that I can't stay awake. I sleep another 5 hours. Then I get up for 7 hours and feel pretty good. At the end of that I get tired so quickly and intensely that the first night I fell asleep at a friends place mid-conversation, and last night on my computer keyboard at my desk. Being properly awake for only about 7h/day is a bit of an issue, but I am getting good deep sleep that I am hard to awake from, so I don't think it is a matter of sleep quality. 
I've also noticed the excessive sleep issue post inoculation. I'm normally good on 7-8 hours of sleep, but now I wake up tired after 10+ hours of sleep, and I get super tired towards the end of my work day.
A new normal sleep pattern
When I started TSO
, my sleep really changed. I started from extreme long term insomnia, so that's one thing. Then the insomnia disappeared but it came back and I had a period of very short sleep cycles. Then it turned into sleeping only 6 hours or so. Because of my history I judged that as inadequate (I was used to sleeping 9 or more hours IF I slept at all, and "they" say we need 7-8.) And actually what happened is that I figured out that the new normal was healthy. I had lots of energy, felt good, etc. Now I find if I sleep too long I have more pain. I find that naps are sometimes appropriate but not often needed, etc. I need to respond to my sleep, there are no particular rules. For me, finding my best sleep cycle(s), and discarding preconceived ideas, was an integral part of my TSO
The appearance of night terrors following inoculation has only been reported by a single self-treater, who explained that, after taking her fifth fortnightly dose of 30 HDC, she experienced night terrors for almost 2 weeks, before returning to “sleeping great” again.
I've started getting night terrors again! I haven't had multiple night terrors in years ever since I discovered magnesium 7-8 years ago. It's like a deep wound that healed and left a scar.  
While a new NA host has reported the disappearance of previously regular night terrors.
I just realized since inoculating with NA
five weeks ago I haven't had a single night terror, something I would experience a couple of times per week prior to this treatment. 
Early sleep improvement
Improvement in sleep may begin early.
I’ve used sleeping pills every night for the past 30 years and after my second dose of HDC
haven’t needed them!😳 An unexpected bonus as I’m on helminths
for Sjögren’s syndrome and RLS. 
) bounce effects: … increased quality of sleep - had first dream I could remember the details of for longer that I can recall. 
I’m 3 weeks post 25 NA inoculation
and last night I actually got sleepy at 10pm, I haven’t felt like that since I was a kid. I felt sleepy and gradually just fell asleep, like a normal person. It was amazing... If this is a permanent effect of NA
I will stay on them forever, even if they don’t affect any of my other symptoms! 
I just realized, since inoculating with NA
5 weeks ago, I haven’t had a single night terror, something I would experience a couple of times per week prior to this treatment. 
Long term sleep improvement
The quality of sleep is frequently improved in the long term.
I've lost that 'tired but wired' feeling that stopped me relaxing properly, and I've started to sleep better.
After 9 months and 45 HWs later I have stopped with all sleeping medications… I am waking up with more energy, going to sleep naturally, and not crashing during the day. I credit the HWs with this improvement after suffering for more than 6 years and trying many different treatments with no improvement.
Yesterday she went to sleep before the rest of us. This has practically never happened.
Two months ago I could not sleep without a dose of salbutamol, and that only for three hours of sleep. It was hell. I thus spent the last two years. I was so worried and so resorted to HT. Now I wake up with the alarm again!
Sleep quality improved beyond recognition. 
My Circadian rhythms have normalised and I am getting 8 hours of solid sleep every night. 
Before I needed a good 8 hours and more - now about 6 and a half to seven is plenty.
His sleep is much better; his hypopnea is significantly reduced. The amount of naps he takes have been cut way back. He doesn't have to sleep fourteen hours on the weekends now. He sleeps better at night because he is much less congested. 
The biggest improvement I have found (5 months into using NA
for ankylosing spondylitis) is in my sleep habits. I take one celecoxib 200mg tablet to sleep at nights where, even with the medication, I still struggled to get a full nights sleep, often waking up at 4.30am. Now I can last the night without discomfort.” 
Dreaming in colour for the first time!
I am currently having mostly fun vivid dreams, sometimes even in color. (I only ever had black and white dreams!)
