"i&#039;m male, 59, suffer from anxiety and panic attacks. it took a month for this medicine to kick in.  stick with it. i sweated like anything at night for the first 3 weeks but that stopped. i wake up briefly at 3:00 or 4:00 am (a side effect) but it is totally worth it. previously i had knots, big suckers, in my stomach for nearly a year. i used to worry and then look for things to worry about and then initiate my flow chart of worry. no more. a positive side effect is lexapro. can also impact/stop obsessive compulsive disorder behaviors too (like counting this and counting that) i also was under-weight forever and have gained weight. a negative is a diminished ability to ejaculate - but again -so what."
