insomnia
"I don't have the typical insomnia. I can fall asleep (very easily, so easily I've almost considered myself to be slightly narcoleptic). But I can't stay asleep, and I don't fall into that deep sleep that you're supposed to. I wake up several times a night and even though I can fall right back to sleep, if you're not getting "restful sleep" then you're going to be tired. Ambien knocks me out! I take 10 mg. I am a 230lb female so I need the 10mg to sleep for 7 to 8 hours. Sometimes if I am just exhausted I can break it in half and sleep fine. But 10mg is perfect for me. But I am co-dependent on it now. I don't mind it so much. It's nice to know I will be rested after going to bed at 10pm and waking up at 6am."
