.. before i give the advice... here is the question... If a person has been on subutex for 2 weeks, 16 -8mgs/day, last 2 days 8mgs. The last 6mgs of subutex was taken at 730am. When would it be safe to take 10 mgs of methadone??? Does a person need to wait 3 days before they can take a methadone??? I am sure they wont "feel" anything from the methadone but will a person get sick if the subutex is still in their system even if at a minimal level?
