Half an Ambien wasn't working and I didn't want to take a whole. One Advil PM wasn't doing the trick and, besides, they made me too thirsty. I tried 3 mg Melatonin the last several nights, but was wide awake at 3:30 - 4 a.m. So annoying. Last night, I popped a time-release 5 mg Melatonin and - voila! - a blissful, 8-hour night's sleep. I came to semi-consciousness around 3 or 4 (didn't look at the clock, deliberately) but drifted back to sleep after ten minutes or so, no problem. And, there was no drowsy, foggy hangover this morning. Let the productivity begin! Happy Thanksgiving to everyone!
