I had that the worst when i first went into ketosis! my arms were FREEZIng every evening! warm baths & extra layers help! least we arent doing LT in the winter lol!
Take it as a sigh that your losing your insulation layer! lol Thats what I always think. Although work colleagues may be getting fed up of me putting the extra heating on as they melt!
I get the chills a lot too since starting. Am glad there's a radiator right behind my chair in work!
I find that a nice hot cup of tea does the trick (fennel is my tea of choice these days as I can't bear the regular without milk waaah!)
