depression
"I've been taking this medicine (30 mgs) for 1 1/2 years.  My depression is completely gone and was after a month of taking it.  I've battled depression for 45 years and this is great.  I don't enjoy much sleep benefit (only 3 hrs per night) and do see a rise in appetite at night. I think that I've put on 20 lbs in the last year. The weight gain is surely worth the sanity."
