If I were to stop taking my Focalin (dexmethylphenidate) how long would it take my tolerance to it to diminish?

edit: I guess I should mention that I'm on 5 milligrams twice a day after taking it for about 6 weeks.

Bro, maybe quickly edit since the edit button disappears after a certain amount of time, and repost this in the dex forum, where they can probably answer better than the ritalin forum.
I really don't know anything about dex specifically, but I can't imagine abstinence would help you out. Maybe try running a search with that word in the medications forum. Good luck.
