^ I think that's pretty much it. I find if I don't sleep a good length after tripping on 2C-E I feel very fried, cranky and kinda down. Not so sure about food as I tend to skip a meal or two when I trip anyway, and I don't usually have noticeable comedowns, but sleep and hydration are definitely an important factor, so drink plenty, make sure you get plenty of sleep even if it means sleeping in a bit late, etc.
