Mixing is fine, I've done it. The bad thing is whrn you decide you want to stop taking effexor, I've never had withdrawl symptoms from anything as badly as the effoxor. Why are you switching from paxil? (also hard to quit). These are drugs that build in your system tobalance chemicals, but I always felt great the first few days.

For those that are less informed, medication is to be used WITH therapy, the drugs help with immeddiate and physical sypmtoms while allowing you to find out and work on the real problem.
