No, his dr did not know. I went there frantically(being the co-dependent that I am) and told him what was going on and begged him not to give my husband those pills. It was too late though, he had given him the prescription. His dr did tell me that he obviously did not have all the information he needed before prescribing them. Those pills totally CHANGED him. I hated him when he was on them. Even when he wasn't drinking I hated him on them. I felt like I just got my husband back for a few weeks and now he's going to be "lost" again.
