I was put on Lexapro 10 mg for a month then bumped up to 20 mg. I began to feel severe nausea so I went back to 10 mg for about a week then cut them in half and took 5 mg for a few days. I stopped taking it two days ago because I could not deal with the nausea any longer. I was on lexapro for a total of about 3 months (maybe less). I've had dizziness, nausea, vomiting and kigg headedness. I don't want to be on the drug but I don't want to feel like this any longer. How long will these symptoms last?
