"dr put me on 10mg. i have had major sleep problems for years and suffer migraines with aura. for days i don&#039;t sleep at all. 10mg did nothing for me. bumped it to 20mg and while i don&#039;t feel sleepy i do eventually fall asleep if i lay there. usually 3 or 4 am. since i never sleep this was a good sign. also i woke about 730am feeling great. wide awake, not drowsy or tired. no headache which is also not my norm as i always wake up with a headache if i sleep. this has gone on for 14 days now.  while its not perfect, i feel so good all day it&#039;s the best thing to happen to me in 7 years. i hope it continues."
