"i was started on lexapro for generalised anxiety disorder because the xanax i&#039;ve been on for the past few years is now schedule 8.  i have been on it for 10 days now and i hate the side effects so i will not be taking any more tomorrow.  i started out on 5mg for five days and felt nausea, intense headaches, excessive drowsiness, tremors and total lack of concentration.  then i was advised to up the dose to 10mg and things are worse as i feel extremely anxious and haven&#039;t left the house all weekend.  another side effect is extreme muscle jerking through the night.  definitely not for me."
