First time asker... started taking 5 mgs of escitalopram on Monday. Felt OK the first few days, but last night was, well, brutal. Migraine, nauseous, heart pounding out of my chest, irrational anxiety. So tired I could not get out of bed and go to work. Help... when will the side effects subside. I know it take weeks for the meds to kick in, but will I feel this awful until then... please say no? Thanks!
