I haven't actually gotten around to trying Focalin yet, though I may one day. I have tried many of the other stimulants available (i.e. Ritalin, Adderall, Dexedrine, DextroStat, Desoxyn, Cylert, Provigil, Didrex, phentermine, phendimetrazine, cocaine). Adderall is the one I currently take and have been taking for six, seven, eight months or so.
While taking Ritalin, I was unable to handle more than 15mg every three hours (which I realize is still a high amount). I know people who take much more, though, or the equivalent thereof in an extended-release formation.

That's the FDA's page devoted to their ideas of maximum daily dosage for many drugs. I prefer their list as they tend to be more liberal with the doses than other sources. According to them, the maximum dose of methylphenidate per day is 1.0mg per kilogram of body weight; logically, dexmethylphenidate, being half the molecule, would have an upper limit of 0.5mg/kg. So if you're an average guy who weighs 160 lbs. (~72.6 kilos), the FDA seems to think that 36mg/day is the upper limit... I definitely have a problem with this, though, in that I have a problem with the max dose of methylphenidate being equivalent to the max dose for dextroamphetamine. Dex is about twice as potent a stimulant as Ritalin, so I'd double that dosage they provided to yield a max daily Focalin dose of 1.0mg/kg and a max Ritalin dose of *2.0*mg/kg. I'd say you're well within the limits, provided no cardiac difficulties or other contraindications are present.
