I know because Lexapro is fairly new and most insurance companies won't cover it without a dr. authorization because there are other less expensive AD's out there. I was on Lexapro during my last drug combo because I have tried all the others (don't work for me). Anyway, I am now on Lamictal and seroquel, keep your fingers crossed. I believe Lexapro is a really good one from what I have seen in the recovery community. Also I know 2 other folks with MS and it is working for them. I pray it is the one for you. If you believe it will work, it will. I just learned today that I have doubted my connection with my Higher Power because I am comparing it with everyone elses, wow, an aha moment for me. Recovery ROCKS, most of the time, don't it?? Love ya Ray.
