haha, yes even most simple things are very difficult :) I think that is because brain is trying to fight the intoxication and is trying to use all parts of brain at once. Try eating an apple at that state...what a journey, i was just sucking and tasting the apple with my tongue for ages, so much texture and flavor. I think normally we overlook all this and the part of brain that normally do the task is just doing it mostly on background. But when you let different part of brain do it, it is so unusual that the focus is 100%
