i'm a pretty experience opiate user and i just took 50 mg of oxycodone using Cold Water Extraction and I'm honestly having the best opiate rush of my entire life. It hit within 15 minutes of drinking it with a huge rush that im not used to as far as my history with them is concerned(mostly hydrocodone, or hydrocodone with maybe a single small dose oxycodone thrown in as it was all i had). It almost makes me want to use stronger opiates to get an even bigger rush, as this feels so effin good, wow. I feel good and I like it, quick question though. I have some promethazine i was originially intending to use for its anti-nauseau aspects, however i realized by searching for it that it might possibly potentiate the oxy. Would this be bad to take 25 mg of promethazine with 50 mg oxycodone? I dont know for sure it would potentiate it, and i get absolutley horrendous hangovers from opiates (next day, im fine laying down, but if i get up i vomit within a few minutes) so i wanted to take something. i also don't have much of a tolerance right now. wow im high and this is so poorly organized@!
