I don't care if this thread is a couple days old, I want to punt your scrawny 90lb ass. You're the dumbest and smallest kid on RIU.
But more seriously, do a little homework and experimenting. And yes, opiates are dangerous, addictive and all that, but the 5/325 or 5/500 percs and vikes that you have can be fun and they're certainly not going to kill you if you take 3 or 4.
My advice is similar to what others have been saying, expariment, eat a few, see how you like them.
See what they are like, then take it easy for a few days. Withdrawl won't kill you and it won't even be bad if you use them regularly for a week or two, but you might risk feeling a little off for a few days without them, so just take it easy then take a break.
