Insomnia at a dose step: reported experiences — the long version

Gastrointestinal effects overnight: nausea or reflux or constipation at night can disrupt sleep. Dosing timing (morning versus evening) might help if nighttime GI symptoms are the problem.

Worth separating two things that post #12 runs together.

Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.

The correction was fair and I had been repeating something I had not checked carefully enough.

When sleep problems need attention: if sleep does not improve as weight loss continues or if it worsens, discussing with a clinician is prudent. Sleep disorders are real and treatable.

Sleep quality versus quantity: some people report changes to sleep duration; others report changes to sleep quality without duration change. Both can matter for recovery and daytime function.

post #18 answers the question as asked. The question underneath it is different.

Sleep hygiene: basics (cool dark room, consistent sleep time, no screens before bed) matter more during energy deficit because stress and sleep need are higher.

On post #16 — agreed on the reasoning, with one qualification.

Apnoea monitoring: if you have diagnosed or suspected sleep apnoea, periodic monitoring (annually) during weight loss is prudent because severity changes.

Energy and sleep needs: rapid weight loss increases real metabolic stress. Sleep needs might increase even though appetite for food has decreased. Prioritising sleep is prudent during active weight loss.

post #21 is right about the mechanism and I think understates the practical bit.

Obstructive sleep apnoea: pre-existing OSA can worsen with weight before it improves (apnoea-hypopnoea index goes up as soft tissue inflames before weight is lost). This is self-limited but uncomfortable during active weight loss.

I read post #21 twice before replying, because I had assumed the opposite.

Appetite suppression and nighttime eating: if nighttime eating was a pattern, appetite suppression changes that pattern. Sleep can worsen if nighttime waking is habitual and now there is no appetite-based reason to wake.

Thank you for the correction. I have edited my earlier post with a note rather than silently, so the thread still makes sense to read. The error was mine and it was the kind that comes from remembering a figure instead of looking it up.

Stimulants and sleep: if supplementing with caffeine or other stimulants for energy during weight loss, timing and dose matter for sleep. Evening stimulant use interferes with sleep.

Coming back to post #25, because the follow-up matters more than the original answer.

Picking up post #25: that is the part I would want checked first.

Sleep hygiene: basics (cool dark room, consistent sleep time, no screens before bed) matter more during energy deficit because stress and sleep need are higher.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.
