Dear Medic: Thanks for the imput on your experience with Effexor! It sounds like you had a much worse experience than I did. Sounds like the doctors just masked one symptom with another medication to combat the effects of the last one! Whew! What a mess. Are you OK now? I haven't heard back from my doc yet as to whether he'll change my meds or what? No wonder you had heart palpitations. The effexor has stimulants for epinephrine and norepinephrine, according to my doc, and can cause excitability and insomnia. Boy, is that an understatement. I have an excellent internal med doctor who actually listens and is trying sincerely to help me. My rheumy is not sympathetic or compassionate at all, so I'll stick with my int. med. dr. At least your neuro is is a good one. Best of luck. sue ps: are you really a combat medic???? I'm an RN.
