Bah, you guys need to meditate more. I once took 500 mics of LSD and flipped it with a fair amount of MDMA at festival when I had a screaming splitting headache and a deeply painful sunburn on my back from the day before. I had a magical trip, one of the most memorable of my life. The headache remained throughout the trip but I didn't judge the pain as bad, just let it be, and like everything else on LSD it just turned into a profound screeching sensation which distributed its effects throughout the entire environment, as though the trees and the speakers, too, were on fire with the same ache. I laid down in the grass and let my sunburn cry out in pain, all a loving symphony of dissonance and a feeling of being alive. The pain surrounded me but it was no longer pain, it just was.
