I saw that episode awhile back. He's still popping all of those pills on his new episodes.
I watched one yesterday which was a rerun where he goes into a shop and buys a cane and picks out one with fire emblems running up the bottom. I am thinking they are referring to the RSD but I haven't heard the term used.

I don't like him though. The show is just so unrealistic. No Dr. could get by with what he does on that show in real life.
