For sure you dont want to cold turkey of the suboxone, its best to taper down especially when your still at 16mgs/day.
With the
adderall, I only have some brief experiences
with it, but I never had a problem when I quit. But I know of many people who have had problems, its an amphetamine, so its very addictive. Hopefully some more people come by with more experience with adderall, Im not sure what the safest way to detox off.
