Clonidine is fine, it meets his request. I too would switch this patient to suboxone for pain, to avoid the dose withdrawal effects he is likely having.

'Tis a luxury of rural medicine to access a bed for this, but I have found that it makes opioid rotation for higher Meq cases, or opioid hyperalgesia syndrome, very smooth.
