Your best bet is to wait as long as you can before doses and even then man the magic won't be like it was, it never will be for us again. You could take things like benzos or stimulants to try and add to the euphoria but they'd have to be low doses of all compounds and IF YOU'RE NOT EXPERIENCED AND I MEAN SUCKING DICK SO YOU AIN'T SICK EXPERIENCEDDO NOT MIX OPIATES WITH ANYTHING ESPECIALLY BENZOS AND STIMULANTS
Ya stay away from the benzos lol0h, I do N0T need to be dope sick in order to suck dick. I do that shit for free.
I'm extremely experienced with both benzos and amphetamines, but have managed to stay away from them for a few years now, and the last thing I need is to be dependant on yet another substance [and benzo withdrawal is fucking horrible].
