I was on Sertraline for physical symptoms of anxiety for about a year - being racing heart, chest tightness, constantly on alert and unable to relax. For me, the side effects never subsided and outweighed the benefits so I weaned myself off them in February. I feel I still need something to relax me and am unsure what other meds would work. I feel I have a constant slight depression also, a 'flat' feeling. Has anyone had success with something other than Sertraline? Thanks.
