It seems like some of us are just non-responders. And it feels pretty universal: HOT-ROX never made me feel jittery (or anything), I've never felt a "caffeine high" or jitters, I rarely (less than a drink a week) drink but still have a very high-tolerance, back in college I tried a couple recreational drugs: non of them did anything for me (a couple made me sleepy), I've been taking sudafed for the past few days to unclog me: again nothing.
Hell, even when I broke my collar bone and they shot me up with morphine (I kept asking for more hoping to feel something and "enjoy the ambulance ride"): nothing. I don't even mess with OTC pain killers for anything, because they don't do anything.
The ONLY thing that has ever consistently altered my mood or performance has been long-term diet and exercise habits.
What's the deal? I know I'm not the only non-responder on these boards.
Does anyone have a good grasp of the mechanism at work here?
It seems almost universal: nothing works. Is there an upside here?
