I usually snort or chew, if you want to snort you have to crush the balls inside the capsule, or if it is a tablet crush that and go over it with a razor well to get it a fine powder.
One will be pretty light, two moderate and all three stronger, methylphenidate isn't a very powerful drug anyways. It makes you feel kinda cracked out, it will be difficult to sleep after you take them and the comedown usually doesn't feel too great.
