So, tomorrow I want to do some Methylphenidate (ritalin, metadate, etc) before I go to school. I have (1) 30mg Metadate CD and I'm planning on crushing up the beads inside and parachuting them. I weigh 100 pounds, so I'm a lightweight. I have no tolerance. My question is: how many mg's should I do? Keep in mind I'm going to school, so I don't want to be too fucked up.
