perhaps next time you should elaborate on your dosing. its as simple as this....if you ingested 80mg or 40mg for that matter in anyway and you are an opiate "virgin" or just new to them, you should have been nodding pretty hard with plenty of euphoria and itching (esp w oxycodone)
NO shit lol , when i first started doing opiates i had a shitload of percs took 2 , nothing happened execept slight relaxtion , took 2 more moderate itching and slight nodding but stupid me thought that instant meant "instant !!!!!" so i took 2 more definatley nodding out and about 2 hrs later took 1 and half more and my fucking eyes rolled back into my head and i was passed out for about 4 hours ...
and i was 230lbs at the time with minimal opiate experience , except for some percs that i got for my wisdom teeth and some fent / morphine when i was 13 ..
when i finally came around to oxycontin about 2 years after this without taking anymore painkillers i did a 20mg line and definatley felt it .. and my body weight wasnt too far off from that previous weight. and i was nodding out on the couch for a good 3 hours .
so it is possible to take a "First liking" to opiates and be able to feel them .. because even when i was 13 i definatly felt when the morphine entered my IV and i wasnt even into drugs at that time .
