Nights are always tough for me. I always seem to feel lonely and depressed. If that wasnt bad enough i have trouble falling asleep due to my depression/bipolar. I even take seroquel (400 mg) at night along with lamictal (100 mg) to help me fall asleep. That just really makes me a little tired . I take ambien (10 mg) used to knock me out. Now i take it i can stay up for hours.
