I've only been on effexor for four months 75mg. I had taken prozac for 13 yrs due to some anxiety issues. I didn't feel that the prozac was helping me anymore so my Dr. switched me to effexor. I wish I had done more research on this drug- but I just went along trusting my Dr. my first symptom was an increase in anxiety! I started picking at my skin horribly and my blood pressure rose. After my next visit with my Dr. we decided that I should go off of it slowly. I can't believe how awful I feel- dizzy , tired, and sick. I'm so upset with myself for not looking into this. I'll be turning 50 in a few days and I feel like I've hit a low point in my life. I just want to feel better.
