I take the same dose of Effexor XR but all three tabs in the morning. The side effects did seem to pass after a week or two.

Effexor works great for me but it's really hard to get off it if you ever want to. Since I can't ever get off it and stay well anyway, I've reconciled myself to that drawback. I've tried Lexapro, Zoloft, and Prozac and Effexor is the only one that seems to work for me.

That does sound like a lot of clonazepam though. Do you take it for panic? I wonder if, once the Effexor builds up in your system, you will still need it? Have you told your doctor about the drowsiness?

Effexor is one of the SSRIs that works on anxiety too, so it might help you in the long run if you give it a chance. Good luck!
