After over 4 years of MMT,tapering down and switching to suboxone for 2 months (with a somewhat fast taper), my son still has physical withdrawal symptoms daily after 3 months of NO opiates! He is very frustrated, to say the least. We can not find any info about this or what to expect or do about it. We are beginning to explore alternative medical ideas. He is afraid that his brain is permanently damaged and that he will have to return to MMT in order to function. Does anyone know anything about this situation?
