I've been taking Lexapro 5MG for about 3 weeks now. I am about 6'1, Male, 120-130 pounds. The first 2 1/2 weeks on Lexapro I felt pretty good. Before I threw up everything and didn't want to get out of bed cause I was nervous about my anxiety. Now ever since last night I had a panic attack with all the bad symptoms. Now I feel back to my old bad self. I can barely eat now without almost gagging and panic attacks frequently but not with all the symptoms like last night. Is Lexapro 5MG too low of a dose for me?
