Ironically if you want to get more of a high out of suboxone, you need to take less, not more. Lower your dose below 1 mg daily, then like the above user said wait until you are in WD and when you take your .5 or 1 mg dose you will feel some nice glow and a mood lift. You can't get high by increasing your dose because your receptors are already full after taking an 8 mg dose. Bupe has a ceiling effect and taking more quickly results in diminishing returns. Instead you want to take as little as possible and then you can actually feel your doses.
Taking very small amounts per day has the added benefits of making your supply last way longer and making it much easier to taper off, plus it has fewer side effects. There are very few downsides to taking less. The only one I can think of really is if you are serious relapse risk and the only thing keeping you off heroin is that your receptors are full enough to block the effects of heroin. Even then though, there's nothing really stopping you from just waiting a few days for the suboxone to wear off and then doing heroin but hey if people think loading up on subs keeps them off heroin I am not here to tell them different.
