"the only problem i have is constipation and urination.  it&#039;s very hard to get a stream going.  this is the best pain pill i have taken.  i know everyone is different, but what quantity has to be taken before having withdrawal symptoms? 

at the present time i take (1) 4mg every 4 hours.  i hope to cut it back to (1) every 6 hours.  i have never had any pain medicine as fast acting as this."
