I took prozac max dose for many years and it quit working,I have major PTSD and depression and tremendous pain in hips and legs due to arthritis. I was taken off prozac and given these other drugs to controll my issues, Can prozac over this amount of time make your brain inhibit the effects of these other drugs? Seems I now have a high tolerance for thes other meds and what I get prescribed does not help much, Please answer if you will . It has been very depressing and I also fight depression. Thank you.. DJG
