pain
"The only problem I have is constipation and urination.  It'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."
