im took my last percocet sunday, started suboxone monday(4mg) then tuesday early afternoon (8mg) and wednesday i felt good except for some anxiety so i took 4mg at 5pm i feel fine really. basically, i wanna know if its because i havent taken pills in a few days that i feel good or if the suboxone is still working that makes me feel ok. how long does a 8mg dose last? thanks!
