Recently I've been going back to Robert Fisher's old posts on his Classic D&D (or was it OD&D) campaign from many years ago. Reading these was a big part of what got me back into older editions of D&D.
Looking at them again now, I realized that my "big idea" for energy drain the other day was actually just Robert's idea from a dozen years ago or so.
So thanks (again) for the idea Robert! It obviously stuck with me somewhere in the back of my mind.
