Sounds to me like Heroin just isn't for you, Maybe instead of finding a good substance to make the Heroin enjoyable, only do said good substance. If you don't care much for "the nod", and you're looking for more of an upbeat, energetic feeling, but you want to stick within the realm of opiates/opioids, I would suggest something derived from the thebaine alkaloid(Oxycodone), opposed to morphine alkaloid(Heroin) , In my experience Oxycodone has given me a non-drowsy, clean, energy filled feeling, where as Heroin can leave me feeling sluggish and tiresome. I'm certain the sleeping pills the salesmen are cutting it with adds to that tiresome feeling! However I'm speaking of diamorphine hcl, not blacktar, never did blacktar as I'm from east of the Mississippi, but one would think that would make you drowsy too..
