"i have been on lexapro for almost 5 months now and i am doing great. it has really helped a lot. i don&#039;t have the negative thoughts like i did and i can actually have positive thoughts. the only downside that i see is the drowsiness. but i am super sensitive when it comes to medicines that &quot;can cause drowsiness&quot;. i can function but i go around yawning a lot. that is getting better though. i have tried taking it before bed to see if that would help."
