I cannot say
how oxycodone will make you feel
in comparison with methadone. I can however, share that in my experience, oxycodone is a much less debilitating medication. It causes less somnolence than methadone, and is not as effective as a pain medication.
For some who get great analgesia from methadone, other medications can help with the side effects. For example, I used ritalin for the years I was using methadone.
