dude, do a search and/or go to erowid. if you can manage to get your lazy ass to read even the most recent three pages of pandora's threads you'll see about 10 with the info you want. sorry that was a bit harsh, but come on this has been covered 1000 times over.
snort it i guess... It isn't a big dose of ritalin, it's about 1 bump worth (for me) you will feel it's effects in moderation but nothing likr 4-5 pills.
It really depends on you.. How many times have you popped ritalin? Because, i know now 40mg of riatlin wont do shit for me. Im guessing this may be your first time. If so, you should be good.
