Dude, caizar... I have read posts regarding your heroin usage and possible withdrawl symptoms. If you do heroin at any regular frequency, you will not feel tramadol at all. Seriously. I used top take 2-4 percocet 10's when I was 17 and first started opiates. But after I started iv'ing 20-100 dollars a day of dope, I went back to percocets after a brief period of abstinence and found out I now needed at least 50 mgs of oxycodone just to feel it at ALL.
So man, if your trying to get high.... do heroin. And if your trying NOT to do heroin..... Use tramadol sparingly along with other benzo's and otc remedies for w/d.
