I feel silly for so much preparation, but I intend for this to be a one-time-thing, and I want everything I can control to be perfect.
LSD can teach you more than what you will probably get out of one trip....
Your plan sounds pretty good, although peaking at sunset is pretty beautiful.....
Don't forget a flashlight or some source of light, i have wandered around the woods on 500ug, and 250mg MDMA without any source of light other than my cell phone and while it was interesting, i would rather have had a flashlight because i got lost as fuck there for a little while....
As far as food to bring, go with fresh fruit.... Pineapple is wonderful, a fruit salad is like an adventure for your taste buds.... and honestly fruit is really the only thing i enjoy eating on acid.... Meat products just feel wrong, and vegetables just lack the flavor.... Oh and for drink, any type of fruit juice is wonderful...
Dont worry so much about your meals ahead of time, eat a pretty decent meal before your trip, something easy on the stomach..... Your probably not going to be hungry for a while, so eat a decent meal beforehand, and snack on fruits and whatnot during the trip.... There isn't a lot of vitamin preloading as far as LSD is concerned.... You can trip face even when your diet sucks, i tripped an entire weekend on a multitude of designer drugs, mushrooms, and nitrous living on oranges, poprocks, pixie sticks, 2 pancakes, and various other invented snackstuffs while tripping like the oatmeal cream pie sandwich filled with fruit snacks and pop rocks....
as far as staying awake goes, expect sleep to not come very easily for about 14 hours after dosing.... I can trance out, close my eyes and open them hours later feeling like it was just a short time but i really can not call that sleep..... I can do this on every psych i have tried it with, even DOM which is speedy as fuck.....
