"To sleep, perchance to dream..."
I fall asleep like a rock for about 3-4 hours (especially recently - long story), but if I have to get up in the middle of the night - heaven help me. What I've found that seems to help is 900 mg of gabapentin (this is an off-label use) about 2 hours before bed - it keeps me groggy until about 8AM so I have a chance.
Scott, ask your Dr about Trazodone (a mild anti-depressive often prescribed for sleep assist). A half little 25Mg scribed tab, so 12.5Mgs. I've read up on published side effects and don't have a single one (going on a year now) (many have no side effects at all). The web says, 30-60 minutes for drowsy, for me it's 5 minutes (but I take it and go right to bed). I fall asleep quickly and stay asleep, every night. But I must get up 2-3 times a night (6 steps to pee and back, and avoid thinking about anything at all) and return to sleep immediately. But only 6.5-7 hrs, never 8 or more. But good restful sleep and everything that brings with it. With no down side of any kind.
(I have no depression, and own no stock in the company either)
EDIT: By comparison, I years ago took the mild anti-depressive Chantix to try and help me kick tobacco. It made me sick to my stomach every time, and made the cigarettes taste bad, but did not help me stop smoking and I flushed them down the toilet in short order. Nothing works except dogged determination and resisting the urge to do violence to people while quitting.
