"about a year ago i lost 8 pounds in 1 week, two pounds more the next week. i couldn&#039;t sleep and constantly felt nauseous. my doctor ran every test under the sun and came back with only one conclusion:  panic attacks and severe anxiety. after i got past my initial thoughts of thinking he must be a total idiot, i asked for lexapro.  i did 5 mg the first week, moving up to 10 the week after.  as my md warned, the anxiety initially increases, so keep the xanax handy. two weeks into it i started having longer and longer periods of normalcy. then, on week three it&#039;s like it suddenly stopped and sent me into a tailspin right back to where i started from. my pscyh told me to go to 20mg because i didn&#039;t have quite enough. worked like a charm!"
