The question is, do you think you have depression. I guess you will know soon enough when the Celexa is completly out of your system. I have had no side effects to speak of with Effexor, among others that I can't think of right now. If you think you need an antidepressant, you could cross tritrate, i.e. gradually lower the dosage of Celexa, while at the same time, gradually increase the dosage of Effexor or some other SSRI or SSRNI. Best of luck. I know you want to get back to your exercise ~ billiebluecat
