depression
"When I was taking this JUST as a smoking cessation aid, I couldn't sleep EVER. Not even when I took half the prescribed dose and took it early in the morning. It made me crash, made me irritable and couldn't eat. But now I take it for Major Depressive Disorder and as smoking cessation, and even on 2 tablets (300mg total) I fall asleep! and not at night time...it makes me fall asleep during the day, especially after it kicks in. I can take it at 5pm and fall asleep at midnight or even before, take naps, etc. This is the only antidepressant I will take, because SSRI's do not work one bit for me. They make me feel more depressed. Wellbutrin does help my moods though. I don't get fits of rage when I take this anymore like I used too."
