I have been taking opiates on and off for like two years and I have a tolerance to most opiates. It takes 20 mg. of oxycodone to give me the perfect high without nodding off. I have taken 50 mg. of oxy once and was fine, I just started nodding off. But one time I took six 10/325 nocros over the course of like three hours and almost died. Seriously. I got triple vision and my breathing was so bad I had to concentrate on it. I was puking every half an hour and eventually it was just dry heaves. But how can I handle 50 mg. of oxy and not 60 mg. of Hyrdo? I know oxy is way stronger so how did i get so fucked of 50 mg. of Norco?n I also got strange hallucinations on the Norco.
