Granted that's a relatively low dose of methadone, the bottom line is that you should never come off methadone cold turkey; it could be lethal. reason is because methadone has a half-life that's longer than any other drug of its kind, and after 3 years, methadone has sunk deep into your bones-- it could take 3 weeks or longer to get it out of your system. whenever coming off methadone you should be professionally detoxed, period. methadone is a bitch, the worst kind of opioid bitch there is. i can't comment on the ritalin.
