Vickie, I'm thankful you posted this. While I wasn't on methadone, I was on another medication (that I'm no longer on) and I discovered the same type of reactions (not as severe, of course!)....and I thought I was going a little nuts because I couldn't rationalize the changes in vision, hearing, taste, cravings,....
I know every med works differently on people, but when I got to read of your experiences, I felt much of my sanity drip back.
I'm so proud of you, and I'm also very encouraged, reading of your journey.
Why, you maverick you! :)
M.
