At first you get a little light headed
then you start to feel warm and cozy and your eyes go fuzzy with your eyelids feeling heavier than usual.
you will laugh at random things that are normally not funny and everything you eat will be the tastiest thing ever.
You will have no concept of being full and you will end up eating a whole box of cheerios with out even realising you had them in the first place.
Time slows down and every movement sends waves of heat over you. You will speak slower and forget words halfway through saying them. You will never find anything so comfy as what you are sitting in while high.
If you fall asleep when high, when you wake up you will feel so great.
In short, heaven is probably in the clouds because everyone is baked up there.
Man im so high right now, i can see that flys wings moving
