I started peating about a month ago. Just had beef liver for the first time as a simple liver and onions fried in butter around 7pm. My body started to heat up about 5 minutes after I finished eating and I was full of energy and warmth for the entire night. So much so, it was difficult for me to sleep until midnight when I am normally out cold by 10pm. I can't tell if that is a good or bad thing...
