Hi- I actually use the Stabilium for mental clarity and physical stamina. I have given it to patients who said they slept better. It did not help my sleep. If I take it too many days in a row I can't sleep!!!!!Nothing seems to help my sleep. I tried ZMA and was awake half the night even though I took earlier in the day. The only thing that helps is Xanax and even that is a bandaid. I am just super sensitive about sleep. This was my first symptom years ago. I believe it's tied to hormones. It has been a frustrating journey but I know I'll stumble on the right thing eventually. So... I'd be careful about using the Stabilium for sleep. However, it can pull me out of a flare at least partially and helps my thinking enormously. Hope this answers your question. By now I've forgotten what you asked. Better reach for the Stabilium.
