The major difference is a surprising one. I seem to have longer, more linear dreams, with more "plot" and less random jumping from one unrelated image or sensation to the next. I also don't sleep for as long most nights. It will be interesting to see whether these effects last.

Also, as with quitting cigarettes (or so I am told) I find that food tastes a bit better. All the lung clearing stuff seemed to happen earlier when I was merely reducing and that's certainly been a joy.
