... 4th week of the transition and it is getting more difficult. Week 1 I stepped down to 75mg, no issues. Week 2 stepped down to 37.5 and started 150mg of Welbutrin, still okay. I have stopped taking Effexor XR altogether now as of 7 days ago and just on the 150mg of Welbutrin... not doing too well. I do not want to regress to back to the Effexor XR. I hate the drug and want to leave it behind once and for all... Anybody else experience this horrible feeling? more importantly, did it pass and how long did it take to pass? Any feedback is greatly appreciated!
