insomnia
"Prescribed for really bad insomnia that started 6 months ago. 15mg did nothing. Tried 30 mg the next night and slept 7 hours. No side effects and woke up feeling great. Took another dose the night after and slept great again. Then it seemed to stop working the 4th time. Tried 45mg the next night and was awake at 2.30 am.  Frustrated. Doctor said to keep taking and that I shouldn't be taking 45mg.  Hoping it will work tonight."
