OK, I don't want to jinx this, but since I starting fasting (one day a week, for health benefit) about 6 weeks ago, I think I feel happier. This could be coincidence, of course. But things in RL have acutally been pretty difficult, and yet the fast day itself, whilst difficult, feels like it gives me a real boost. Feels like a proper chemical change, IYSWIM.
My weight hasn't changed (I didn't want it to), so it's not to do with that.
Anyone else find this pleasant mood effect? Is it "real"?!
