"i was told about this medicine about 10 years ago.   at the time i could only find the original strength, and quickly found out that i could not take during the day because it knocks me out and i will be sleeping.  it is the only medicine that will take away the pain i am having.   i had knee surgery twice in a year and the prescription pain medicine i had took away some pain,  but with the percogesic, the rest of the pain went away and i got to sleep.   i tried the maximum strength last year for the first time and discovered that it didn&#039;t make me sleep. ...actually hyped me up.   i discovered it was different than the original strength by having an antihistamine in which i am sensitive too.  so now i can take during the day. its the best!"
