I would reccomend taking adderall constantly..that is if u can get it. Adderall is a hell of a buzz, personally taking 90 mg once and getting stoned as a mother fucker i can tell u u'll usually be ok. On erowid it is said the l.D.50 for most humans is 400-500 mgs. but thats very true w/ adderall after taking a decend dose of it u feel like the your the shit, and after extended adderall usage and stopping suddenly will lead to extreme irritablitiy. For example the next day everything people say to you will piss u off if it wasn't sompthing u wanted to hear. So u wana be carefull with that cause it's a good way to get into fights with people. thats about the extent of my adderall advise for ya.
