Well, for the Benzo catagory I would go with Xanax, Klonopins are nice also, but Xanax just has a kick and gives me euphoria instead of just chill/anxiety relief like klonopin or Valium. For opiates I gotta say Morphine outta all of them(well ones I've tried still havent REALLY tried opana, ate 20mg a few years back but no snortin or bangin so I feel I missed out. Roxy and Diludid also, but the reason I say Morphine is because of the legs it has. I can do a Morphine and be good for a while, but with dillies/roxies its like a few hours later I want more, so morphine for the legs. Those are my favorite fun opiates, but my favorite unfun one is Suboxine for keeping me, well not strung out...does the job for the most part, though Methadone would be better for me...sorry ranting. For uppers I gotta say Desoxyn even though I've never had it, just street meth, but it is Methamphetimne so imagine it's pretty similar,just enjoy my uppers for special occasions.
