"first day taking lexapro 20mg i experienced fuzzy vision, tingling sensation in my arms, yawning, and tiredness. second day i decided to take it before bed, woke up 2 hours later with nausea, weakness, dry mouth, dizziness, vomiting and tingling in my arms. talking to my doctor tomorrow to see if i should switch, not taking it tonight. my anxiety did subside in the last 2 days though."
