"the 10mg didn&#039;t seem to help at all so after few days they let me up it to 20mg. i had a little trouble sleeping my legs would twitch and it made me feel really angry for few hours. i took tylenol pm for a couple of days after upping it and it seemed to calm me down so i could sleep.  then i was fine until it was time to up it to the 40mg.  i could not sleep at all, my whole body would twitch and i just felt out of it and like i was going to have a panic attack.  finally took a bath and it helped me relax enough to sleep for couple hours. it was very scary but after a couple of hours i felt fine. i am a little scared to take the second dose of the 40mg but i think i&#039;m gonna try taking it in the morning.  i feel great on the medicine. other wise.."
