"An episode I hoped I'd never have to record, but one I felt I owed to all the beautiful Armcheries who have been on this ride with me for the last couple years," Shepard said in an Instagram post announcing the episode.

For the last eight weeks, he said, he had been "on them all day," after taking them originally for injuries.
This led to a situation where he was "taking, you know, eight 30s a day, and I know that's an amount that's going to result in a pretty bad withdrawal.
And I start getting really scared, and I'm starting to feel really lonely.
