Hi Kimmie, are you due on your period?? On my 2nd day of SS i came on my period and i was sweating rather than feeling cold. But now my period is finished, i am absolutley freezing, its horrible.
You've had a fab week 1 loss so you must be in Ketosis, so i wouldnt worry about it too much as long as your stil losing weight. Make sure you keep drinking your water to replace the water you lose through sweating.
