opana was my drug of choice for a coupla years, thought i would NEVER be able to leave it alone!! i started out snorting 30 mgs. in the morning, and 2 more times. i was in car sales at the time, and i ran my ass off around that car dealershio all damn day! i sold about 40 cars a month, and made a ton of money, and had a blast doing it! the party came to a screeching halt when i ODed, almost died. so, my msg. is, not to be a buzzkill, but be very careful! i snorted 2 - 30's at once, wanting to get a killer- HIGH!! i went out HARD, passed out on the floor, alone in my apt. for 8 hours. woke up as if nothin happened, and had to be at work in 2 hours! i continued doing O's for awhile, only stopped when i had to move to another state for a year, then got on suboxone. that shit is the best high ever, but it can kill ya too. i miss that buzz, but i'm damn lucky to be alive.
i know your question is about amount, and tolerance.
i am female, 5.6" & 130 pounds, so pretty small, i guess. my tolerance is crazy! i used to take 26 lortab 10/650's a day until i switched to opana. just enjoy, but be careful!
