I cannot believe that her doctor told her to go cold turkey - absolutely horrible advice. She should have tapered off of Effexor extremely slowly. Typically it takes about a year to completely taper off. I'm just in shock that her doc told her that.....I missed one pill once and had all of those symptoms - it's miserable. I can't imagine going through that for long. If she does decide to go back on the Effexor to taper off before going on the Wellbutrin completely, PM me, I can give advice on tapering off.

On a side note, I sincerly doubt that any antidepressant would have anything to do with what Andrea Yates did. It sounds more like schizophrenia, since she claimed to hear voices. Typically, depressed people don't tend to hurt others, they are more likely to hurt themselves. Post-pardum depression is a little different though, so it may have played a part, but I believe that Andrea Yates claimed that Satan was talking to her and she drowned her kids to 'save' them from hell (I think that's what she was claiming).

Good luck to your mom, and I hope that she can get through this!
