I posted part of this on another thread, but as it's an interesting phenomenon I wonder if anyone else has the same experience on Sub:
While opiated I was always nice and understanding, H or
methadone and even when I was craving I never got real mean.
Strangely enough, I nasty and almost violent a couple of weeks into Subutex therapy. I would snap to people for no obvious reason, make mean remarks and generally put people down for absolutely no reason. I have the misfortune to often be around people who consider such behaviour normal so it didn't register for me until I started being real nasty to my wife who had been nothing but understanding and supportive.
I am not an excessively violent person, but on Subutex it took very little for me to lose it and start slapping or at least make very serious threats, way out of proportion to the perceived offense people made.
My sense of humor got very dark.
This unexplainable nervousness and strange behavior went away when I started working out a week ago. I push myself real hard on both cardio and weights and it seems like the endorphine factory re-opened, I actually get a pleasant high after exercise (only aerobic does this though, weights only do not make me high).
Sub does the trick in some ways (I can perform sexually for instance and have the desire to, something I almost forgot about while being opiated),
Another thing on Sub, at least for me, was that I did not get my energy back. I was as lethargic (or lazy) as on H or methadone. Most people report an energy boost almost high-like in nature, I felt nothing of the kind, but again, exercise helped.
One thing ever exercise doesn't help with though, too often I find myself in deep contemplation, not a bad thing per se, but I feel as I were less social than before, as if I am content (if not happier) being by myself.
Weird thing, opiates, but nothing beats the weirdness of Bupe.
P.S.
To make it even weirder,
cocaine doesn't work for me anymore. As much as I tried to take and as good as it was, I feel absolutely nothing. I smoked base once while on Bupe and only felt physical discomfort. Not a bad side-effect, just unexpected. Ganja works though.
