"i have been on lexapro for about 12 days (never been on anything like this in my life). i am very sensitive to the medicine. i can take about 2.5- 5mg. i have some shakiness, and had increased anxiety in the beginning. it seems to be leveling off now. my doctor recommended that i take 5mg in the beginning and then increase to 10 mg later. i think 5mg is enough for me. i get night sweats as well. lost weight, because i am not hungry; nauseated. the anxiety has decreased. its working."
