I don't know of a painkiller that doesn't have a rebound effect of depression, but I do know of certain vitamins and minerals and amino acids that can help when quitting hydro and it's other opiate counterparts.

L-Tyrosine combined with B6 is a tremendous help (taken on an empty stomach in the morning), as is 5-HTP and SAMe. These have made a potential 3-4 week bout of depression after quitting hydro last only several days. Of course, I would check with the pharmacist or your doctor for any contraindications.
