I don't have a tolerance. Did a few 10 mg percs a few days ago but before that my last opiate use was years ago. 30 mg had me ROCKED the other day. i took 30 mg tonight and I feel a slight euphoric buzz but nothing compared to last time. Did my tolerance really develop that quick? It's the same exact type of pills (IP 204). It's been an hour and a half...and I'm wondering if maybe they are just taking a long time to increase the high? It was taken on basically an empty stomach orally
