I got IBS-C after starting Wellbutrin, which is an antidepressant. Has anyone else had IBS-C result from an antidepressant? I love everything else about Wellbutrin, but the IBS-C might drive me off it. The IBS-C is becoming worse. I can't take any SSRIs (set of mania--I'm bipolar), and tricyclics cause constipation, so there's really no other option for me besides Wellbutrin.
