In a case resembling this you need to sermon to your doctor. You can't just switch them from one to the other lacking a doctor's approval anyway. If you have Prozac already, I wouldn't recommend stopping the Effexor and starting the Prozac again lacking at least discussion to a doctor or pharmacist. Just call your local pharmacy and explain your situation. The pharmacist will be glad to endow with you some advice.
You should settle to your current doctor ASAP and see if you can get plenty samples of Effexor to go and get you through until you get a bright doctor. It's not safe to switch drugs on your own approaching that, especially that abruptly. Effexor can enjoy wicked withdrawl symptoms.
