I can tell you from recent personal expriance, that 15 hours after taking a 8 mlg dose for 6 days, i sampled a try at my usual of opiate of choce and did my usual dosage, i felt no blocking from the subxone and might add that it felt the same as before i was taking the
suboxone. BUT ALSO REMEMBER that i have only been using suboxone for 6 days, and have only been taking 8 mlg's a day and a couple of the days days only took 4 mlg.
I do not advocate the taking of any drugs for other than personal Health related issues. But have done my share of abussing them in my life. NO FUN..
Good luck and please be CAREFULL.. Im new to the site, and see alot of differnt views, opinnions and such. It would be horrible for some one to go back to the amount they were ussing before after reading that some one needed twice as much as before suboxone, and try it and OD after tollerance was not as high any more. I had the same question as you until today. I can only give what happed to as being MY OWN expriance. REMEMBER, everone is differnt to how they react to any thing. Caution and prudence always..
