This is the way i like to do it and it works very well,
First always drink ice cold water, the colder the better, drink so much you piss every 10 minutes, you will know when to stop before it gets dangerous so drink a shitload. Smoke weed alot! smoke ciggarettes alot! go to the bathroom alot, do anything you want to do, think of what you want to do and do it, if you can replenish the seritonin as its being released you can completely skip the groggy afternoon, drink alot of antioxidants before you roll too, like that new green tea with egcg. also my buddy loves drinking redline energy drink its 390% vitamin c nothing else, yea every sip you will feel, he says but you have to drink alot of water because it dehydrates you, and dont drink the whole thing, you can feel nasty if you drink it too fast. and i saved the best for last, hopefully you stuck around for it, have someone who's peaking or really fucked up to lay down face down on carpet, with his/her arms straight out infront of them, palms down. now stand about 2 ft infront of their hands and tell them to completely relax every muscle in their entire body and to close their eyes. now grab around their wrists but make it comfortable and slowly lift up and slightly pulling twords you (not enough to move them) and make sure they are completely relaxing, make sure their head is hanging and they arent holding it up. when their hands are a little less than 3 ft off the ground hold still untill they make some sort of sound (ohh shit, hellyea, oh my god, etc) and dont forget a slight pull twords you still, now if your hands arent already slipping make them slip a little bit, it ruins the effect if the person your lifting thinks your about to drop them, just as you start to slip lower him down very slowly! and the arms have to be the last thing layed down, it feels like the victim is getting sucked into the floor right after you hold still and from then on it gets more and more intence once i went so far under the floor that i almost grabbed the core! try it its soo nice! i like to find the people who are madd fucked up and tell them you can make then feel better and then once your done they stay on the floor facedown! hahaha i love it
