"i was given this medication after a series of painful surgeries.  i took 100 mg every 4-6 hours for pain.  this medicine did relieve all of my pain.  it made me a bit itchy.  the problem came when i tried to get off of it 3 days ago.  i&#039;m having severe anxiety, which i&#039;ve never had before.  my doctor said its withdrawal symptoms.  i pray i get over this feeling soon.
