i just started ambien cr/er 12.5s, but I dont feel like they are doing anything. I AM able to fall asleep a little bit earlier, but I wake up at like, 5am, and faced with the choice of getting up painfully early or going back to sleep, I sleep. And then I sleep too late. Can anyone share their thoughts on how ambien *should* affect me? 190lb male in good health, who needs to sleep better!
