I heard about this... I’m experiencing the opposite I get so hot like if I have a fever but I take my temperature and it’s normal 🤷🏻♀️. It’s not a constant either like right now I’m actually ok. I was sleeved 3/27/18 have had no problems, no pain, no nausea I’m able to get in my protein up to 70g and my water up to 60 oz. I can say I’ve been blessed that all has been going so well.
