1) Depends on a few factors, like weight, opiate tolerance in general and natural tolerance. I'd keep the dosage at between 10-20mg for the first time, even though u are a relatively big guy. First time I had 20mg I was spewing quite hard. U can imagine the strength of them when docs prescribe endones for moderate to severe pain which are only 5mg each usually.
2) Really depends on ROA and a few other factors. I personally have a very fast metabolism nearly all the substances duration lasts a lot less than for most people. Oxy can last anywhere from 2-5 hours. My favorite ROA is insufflation, oral and plugging. I get more of an effect (initial rush) than orally for example. Prob because it kicks in a lot faster.
3) Its really hard to describe the feeling, the high is more speedy/stimulating opposed to hydromorphone/morphine and heroin which are incredibly sedating. When it kicks in you feel a warm tingly sensation all throughout your body, a similar feeling when u lay into a nice warm bath tub (that ahhhhhh) feeling but it is a lot stronger and longer lasting. You sort of get a nice tingly sensation, quite similar to having smoked some nice strong indica buds. Its like your wrapped in a warm blanket and feel warm, fuzzy, happy and content. Your worries just melt away and you become feeling happy, pleasant and pain free. You also become extremely relaxed.
3) You can do it anywhere, I prefer it in a nice comfy environment like at home with some good tunes to listen to, it gives u motivation to do things but nothing too physically demanding, you can also go out on it to go about doing your every day things, my favorite thing is going to get a feed, I tend to get insane munchies with most opiates (note: some people don't and lose their appetite but I think this varies from person to person)
4) There is no comedown involved. You may feel a bit sad or depressed that your not high anymore but when you wake up after a good nights sleep you won;t have any hangover whatsoever. Having said that if you do end up taking too much you may get sick the next day or even happens soon after u had ur last dose this may include stomach cramps, diarrehea and projectile vomiting depending how much you took. That one thing you need to look out for. In the long term after abusing it for sometime you may become psychologically and physically dependent on it which is worse than any hangover you can imagine which is called withdrawal. It's not a pleasant thing to experience.
Couple of tips id like to mention:
-If your feeling nauseous which is not uncommon for new users make sure you sip on a little fizzy drink and try to stay laying down on your bed til it passed. Its amazing how much it can help.
-If you are taking it via the insufflation route then make 4 small lines, taking off the coating by putting the pill in your mouth sucking on it for 10-20 secs and spitting the coating out. By making 4 small lines taken few mins apart will make sure that the mucus membranes will absorb them the most efficiently. 2 lines in each nostril is the best way say 5-10 mins apart.
-Make sure you keep some travel calm which is awesome to reduce the itching caused by histamine release and reducing nausea, I swear by it

(I use the red box the original one but others like the blue box too, I dont as it has caffeine in it which I dont like during an OC high)
Good luck and make sure u report back to us on how u went with it
