I did not get to a point when clean but I was having  moderate  withdrawals even though they they instructed me to  shave a tiny amount off the tablet each week. They are not a withdrawal clinic but they have a nurse who helps people to cut down their opiates so they can get off of them.  I'm not sure the exact dates I had her help me. I have tried to go off them each year but the withdrawal symptoms are just horrible.
