"i have been on lexapro for about 10 months. i absolutely love it. for about the first month, i was on 10 mg and talked with my doctor about needing more so we bumped it up to 20 mg. after 6 months on being on 20 mg, i felt too relaxed and drowsy, so we have cut back to 10 mg.  i feel great. for awhile, i was really sleepy, but have gotten back in a positive sleep rhythm. looking to cut back to 5 mg soon. it takes a few weeks to kick in, but the wait is worth it."
