"only antidepressant that doesn&#039;t cause weight gain. been on it for 7 years. still have some lows, but nothing compared to without it. did not cause me to lose weight, and did not prevent migraines for me. side effects are more energy. i have been off this medicine and had no withdrawal like other antidepressants. best one out there for someone who has depression with too much sleeping. i love it. and there is no risk in trying it, because there are no withdrawals. you can stop this medicine whenever you like and feel fine."
