I go on and off of keto and find I sleep a thousand times better and have insanely vivid dreams (and not of food). I also do 18:6 fasting like someone else mentioned, and luckily experience absolutely no side effects except wanting to eat my phone in the forty-five minutes before I start eating for the day. I was a chef for thirty years and now sell food to chefs. I know, first world problems but it is hard to spend my day talking about food all day long without feeling hunger. Good luck on round two.
