insomnia
"I took Ambien for a couple of nights, great drug, really works, slept like a baby deeply. Felt drugged the next day but I'm very sensitive to these feelings. Then I decided to not take it again, and had "rebound insomnia" the first night, that was last night. Today I feel very tired after getting maybe 1 or 2 hours of sleep last night. I'm going to try everything I know to get a good nights sleep tonight. Usually I do not need any sleep aids at all. Only took it recently because my sleep got messed up after a travel and being in a difficult place to sleep."
