Hi. I have been on Wellbutrin SR 12hr 150mg tabs for about 3 weeks now after other anti-depressants did not work for me. I haven't had some of the side effects that I've read about like dizziness and nausea which I'm happy about however I have some of the more severe ones. I have increased depression, irritability and I seem to get frustrated over everything. When will this subside? It's effecting my mood and my family. Please help! (I've scheduled a follow up appointment with my doctor)
