I have been taking Bupropion XL 150 for only 2 days. It was prescribed to treat depression, fatigue, confusion, etc. I take it around 8am. I do not really feel any effect, except I am completely wiped out by early afternoon. This wasn't the case prior to starting this medication. The past 2 days I have napped at 3 pm, then back to bed by 9 pm. Has anyone else experienced similar results? Over time will this subside, or is this the wrong medication for me?
