I have been taking wellbutrin for 2 months now after taking efexier. I have been doing great till about 2 weeks ago. Now im so depressed that all i want to do is cry. I had to over lap my wellbutrin because if i dont take it after breakfast and supper i get really bad heartburn. Is this making my med not do right? Do i need to go on a stronger dose? im on 300 mg a day taking 2 150 mg pills a day. Also I went to my pharmist to get my meds and the pill looked totaly differant around 3 weeks ago. Could it be a bad prescription? I just dont see how it could be doing so great and then just stop. I started taking a new prescription now cause i'm now on mail order. So i quit taking the other med and now taking the new one. Please help im misserable!!!
