I was on Lexapro and Xanax for anxiety, the side effects to Lexapro are muscle cramping and joints hurting, my doc wants me to stop Lexapro and Xanax and start .5 mg of Klonopine. I have taken Zoloft,Buspar, and cannot handle the side effects, I have a history of Lymes Disease so I am very sensitive to meds, Xanax has been the only thing that has helped but it is not enough at times, Should I try the Klonopin?
