I haven't coded anything in a good 4-5 months. Been too busy with work. But no, I've never coded while high, since x86 assembly would be way too confusing in that situation (or any architecture for that matter.. sparc, mips, alpha, etc). Coding in C is probably a bit easier while high, but I prefer asm. For me, coding while high would not be good :-P. There would be too many syntax errors, and logical errors. Then I'd be too lazy to fix them, and give up. Thus, for me, it would be useless.
