Well, there are so many fun things to do on e, during and after!...it's amazing. I know probably most of them are pretty obvious because most people do them...but here you go!
1. Vicks (duh). Like everyone else said, blow in the eyes in addition to inhaling through nose is bomb. Eyes feel...and maybe taste? minty! :D
2.
HAND SANITIZER <--- a MUST! Don't feel awkward to put sanitizer on legs and chest or feet. It feels bomb, trust. After the sanitizer starts to dry, begin massaging and scratching (see below). Another thing that feels good is to put sanitizer on yourself (or someone else) and either go outside and let the breeze cool it, or go in front of a fan.
3. Photons (of course). Even looking at the end of a lighted cigarette butt and the fire from a lighter is strangely pretty.
4. Hand/Back/Arm/Head Massages. It feels SO much better if you do it well, mixing it up with scratching with your nails and just gliding your hands firmly over their body.
5.
SCRATCHING arms/back/chest/legs/head with your nails [not TOO hard, and girls do this better cause we have the nails =) ] Also, another trick, in combination with massages and regular scratching::: First, pretend you're a lion or something and bare your claws (so both your hands should be like in a semicircular position?) Then, use your claws (nails) and firmly press on someone's arm/back/etc along with the music. Get it? ANOTHER thing...get one other person and extend your guys' arms out so that both your hands touches both your guys' shoulders/upper arm. Then, have both of you drag your nails on both your guys' arms at the SAME TIME, with your guys' hands ending at the end of their arms. Make it feel a bit better by scratching both inside and outside of their arms (like a little squiggly line)
6. Making occasional menthol cigarette trips OUTSIDE in the backyard for some fresh air, sitting down in a chair.
7. Fluffy ass pillows/blankets and comfy ass chairs/sofa/futon/etc. Hug 'em.
8. Ice packs on your arms/back/etc. So cooolllllldddd and feels good, especially if you're sweating.
9. the "
ELEVATOR". Directions: First, crouch on the ground (having your back facing and being near the wall will be helpful after you complete the elevator) with your arms being X-crossed firmly, but not too strong, on your chest. Also, your head should tilt a bit downwards. Second, take 10 DEEP breaths, inhaling and exhaling (deep breaths as in hearing yourself take in air). Third, HOLD YOUR 10TH BREATH! Then rise up from your crouch at a moderate speed while you're still holding your breath. After a few seconds, exhale.....you should feel a crazy ass head rush.
10. Gum/Sour candy
11. Orange Juice/Vitamin C. It usually makes your roll a bit stronger.
12. Only the best of the best of trance. Play certain songs for the atmosphere and different kinds of songs for different times of the night. Example, when you just popped a pill, you might listen to East Clubbers; when you're flooring it, hardcore trance like "This Is Trance" by Paul Oakenfold, "Lethal Industry (Hardstyle Mix)" by Tiesto, "Ballanation" by DJ Dean is good. When you're coming down, try "As the Rush Comes" by Tiesto, most songs by Kaskade, "Walking in the Sky" by DJ Encore, "Can't Sleep (ATB Remix)" by Above & Beyond, and "Angelfalls" by Ayla. Well, this should be obvious.
13. A nice, long shower even after your roll.
14. Blazing. For one, you have higher tolerance for bud, and two, everyone just gets so dumb and talk about stupid shit...guaranteed laughs! Three, near the end of your roll, if you blaze, it will bring your roll back. Sometimes harder, or just as hard. After blazing, have everyone play the
ALPHABET GAME. Someone starts by choosing a letter from the alphabet, say "F". Then you and everyone think of words that start with that letter. You can also make it harder for everyone else (and yourself when it comes to be your turn) by saying TWO words that start with the letter..and everyone else after that has to think of TWO...and maybe even three. I love playing this game after I roll because no one can think too clearly, and it's funny to watch them think about it. It's also funny when it's before someone's turn, they say "Oooooo I have a good one!" and when it's their turn, they forget. It will happen! This makes you feel so dumb, yet feel happy cuz you're laughing, but frustrated for some people.
15. Going on an amusement park ride. I personally never tried this myself, but some people I know said they went on Space Mountain at Disneyland...and it was the best thing ever. Also, if you go to EDC or Nocturnal, you can have a chance there.
16. Playing WarioWare: Smooth Moves or Rayman: Raving Rabbids on the Wii is freaking trippy/fun/hard!
