I feel you in a sense that I have attention disorder. I tried the meds once and they are freakin amazing. I know what my mind is capable of on them now (2x-10x) but I'm also truly in love with my mind/body/soul as-is and won't cheat on them.
I'd imagine if I did it more often, I'd be a more productive programmer. At the same time, idk what the health risks are for that and I'm already a bit of a hypochondriac as it is... so I probably wouldn't risk liver damage or whatever is associated with long term use
