The goal of this clinical trial is to learn if oral methadone given before surgery works to minimize post-operative pain and opioid usage. The main questions it aims to answer are:
Does oral methadone improve post-operative pain scores as compared to standard treatment? Does oral methadone lead to reduced use of post-operative and post-discharge opioid usage as compared to the current standard treatment?
Researchers will compare oral methadone to a placebo (a look-alike substance that contains no drug) to assess the questions above.
Participants will:
Receive either oral methadone or a look-alike placebo before surgery Receive standard intraoperative and immediate post-operative pain control at the anesthesiologist's discretion Be asked about their pain levels in the recovery area Keep a diary of pain and opioid usage over the first 2 days after surgery
