I have the above available . SWIM's staple is Percoset in 10mg doses. As tolerance builds getting a recreational effect becomes more difficult. I have tried grapefruit juice and tums with minor improvement. Now SWIM wonders if he can use 50mg Demerol tabs either alone or in conjunction with the Percs to increasse the recreational possibilities of the Percs. SWIM also wonders about the hazards of this mix. I also have 5mg Valium tabs available and wonders if they can be used in conjucton with the Perc or Demerol for a better high. Any information you can give SWIM on this subject will be greatly appreciated.
