I find the best things are
1)WEED...This helps give u your apetite back and if u can, the best things to eat(if u can stomach them that is) are: FISH(it contains Omega 3 oils which are good for the brain), CHOCOLATE(its known for elevating your mood and making you feel good, and the sugar gives u your energy back)and BANANAS, these help replace the seretonin in your brain. But then again any food you can get into you is good really
2)GOOD COMPANY, usually best if its the mates u went out with the night before so u can sit around and reminisce about the night, have a laugh, and laugh at eachothers scatteredness, during which the conversation(which was once flowing quite well)suddenly smack back in the middle of the sentence turns to
PERSON A:Oh shit what was I saying??
PERSON B: Oh shit I dont know
PERSON A:Ehh it was probably bollocks
PERSON A/B: (laughter)
10mins later
PERSON A: Oh yeh thats what I was saying before
PERSON B: What?
PERSON A: Ummm...oh no forgotten, doesnt matter
(OR SOMETHING LIKE THAT ANYWAY, U GET WHAT I MEAN)
3)MUSIC, but nothing too hard, u need to be able to chill and relax, not made feel like ur still in a club and should be still dancing
4)A funny, or cool no- brainer movie: Some ideas - Halfbaked, Billy Madison(or any Adam Sandler movie)Dazed and Confused, Baseketball, Night at the Roxbury...ahh the list goes on
5)A comfy couch/bed, coz chances are youll fall asleep wherever youre sitting/lying
