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. It kept me from falling asleep behind the wheel, and improved my ability to reason, greatly.
If the methadone is a good pain reliever (for me, it was the best), ask your doctor if he/she would be willing to try a stimulant medication like long acting methylphenidate or Adderral XL to minimize your methadone side effects.
