I'm really glad it did you do much good.

For me, it was the other way round. When I used intermittent fasting (in the form of the 5:2 diet) to get my weight under control, I stopped snoring like a rhino, and my sleep improved. As did my wife's. :-)

More anecdote: trying to fast of the weight without exercise was miserable. My weight plateaued, and I was permanently cold. Doing some sensible exercise solved both problems. Diet or exercise? False dichotomy.
