Has anyone ever switched from Effexor XR to Lexapro? If so, how did it work? Was there any withdrawals during the weening, switching process? I work in a call center with a high stress level, which causes anxiety and panic attacks. I have been on Effexor XR (75mg) for 6 years, and Klonopin (1mg) for 2 months, my doc has decided to ween me off Effexor XR, so for the next 10 days I have to take Effexor XR 37.5 then start Lexapro (10mg) for 7 days, then Lexapro (20 mg), also continuing the Klonopin (1mg). Any feedback would be appreciated. Thanks to all. :-)
