I just started taking Wellbutrin IR 2 days ago. Doc put me on 75 mg. 1x in a.m. for 5 days then up to 150 mg. 1X in a.m. After reading reviews and experiences, it seems most people are put on 1x in a.m. and 1x in afternoon. Has anyone tried this dose I'm on? I'm wondering if it wears off in the afternoon and fatigue will set in early. Also, on second day, I am in bed all day and feeling very tired and down. I want some energy and tired of being depressed, unmotivated, reclusive. I'm putting on weight and that makes me more depressed. Any information will help greatly. Thanks.
