Struggling with new meds! Was on Ecitalopram 20mg for nearly 15 years, they started to lose their effect as I suffered a bad period of health anxiety after I had a my tests/scans done I decided to asked to be changed. Was put in 50mg of Setraline which has been upped to 100mg after 4 weeks. I feel dreadful, head feels full & dizzy/ off balance, heart races all the time, feel sick, shakey, sweating, etc. Etc. Don’t know what to do, Dr says persevere but it’s so hard when you feel so bad. As anybody else gone through this?
