i think maybe the reason the klonopin didn't help quickly enough is because the dose may have been off. ask doc if you can try it again with doseage adjustment. i too take effexor xr and klonopin for my anxiety and deppresion and it has helped me to cope where as before i couldnt function in daily life. the effexer xr also contains an anti-anxiety property to it and the combonation of the two have worked out well.
good luck. hope you find some relief
