I've been on Effexor (nasty stuff) and Wellbutrin. Effexor is NOT to be stopped cold turkey. The withdrawal is awful. Causes vertigo, nausea, vomiting, headaches. Wellbutrin (or as Catty1 put it "Hellbutrin) caused me to have suicidal thoughts. Like Catty1 said, everyone's system is different. Some people can take Wellbutrin with little or no side effects.

I'd tell your mom to get a second opinion on the meds. There HAS to be something she can take that will help her wean her Effexor meds.

I am currently on Paxil CR, 27.5 mgs/day and doing fine.

Good luck and keep us posted.
