I have been taking 6mg suboxone for almost one year. When I was switched to the generic brand 2 weeks ago and went into withdrawal, so my doctor put me up to 8mg. I am now down to 6mg but after taking my last dose I went into withdrawal again, Unfortunately I decided to take 30mg of methadone about 2 hours after the suboxone hoping it would help with the withdrawal.  which it did NOT. I want to be on the suboxone but need to know when I should again. Also why would I be going into withdrawal while I'm taking regular doses.
