I am not sure how I'm suppose to feel right now because i know everybody's body is different but maybe someone will have a similar situation. So i was on 10 mg of Lexapro for about 3 months and about two weeks ago my doctor upped me to 15mg because i was starting to have slight anxiety return to me, so I'm currently on 15 right now and still feeling a lingering anxiety for a couple days i was feeling normal then bam, it came back to me. My doctors said when she upped me to 15mg that i might end up needing the 20mg. Does it take awhile to even out after upping a dosage?
