So I've been fucking around with tylenol 3, doing CWE to get rid of that APAP... anyways, last night was the first time I acutally got a buzz. it was extremely nice. I'm looking to recreate that experience tonight, however, I've taken 60-90mg doses of codeine last night, and the day before. The day before that (which would be Sunday) i didn't take any, and Saturday I took 60mg. My question is, if I try to repeat the experience again tonight will I have significantly less of a buzz? I have no idea how fast opioid tolerance builds up, and if there's a chance that it could have built up to some degree and cause a diminished experience, i dont even wanna mess around with it. Oh, I should note that it was Diphenhydramine that helped me get that buzz, I read from a few places that it was an opioid potentiator, so I popped 50mg and bam, buzzing sensation all over the body... was real sweet TLDR version - took 1 codeine dose (ranging between 60-90mg) a day for the past 5 days, with the exception of sunday which I took no opiates. I've never done an opiate in my life until the first in this series of days. Will I have established any form of tolerance?
