I wake up several times at night as well. Do you wake up too or do you sleep the whole night through?
I almost never have a problem going back to sleep as long as it is dark. if the sun is up i usually have a hard time falling back alseep. i have thick black curtians in my bedroom for this reason.
i wake up at least once every night, either to piss or just for no reason.
Falling asleep the first time is the hardest part, but i have found that meditation works very well unless i am really stressed out and my mind won't stop racing.
i think my problem is anxiety.
ZMA, L-tryptophan, Benedryl all work well for me.
