I am on Day 6 of 15 pre op liquid diet and the last 2 nights I have been so cold I start shaking. It is not low blood sugar, I am just freezing cold the minute the sun goes down. Anyone else?

Could be, maybe you don't have the best thermoregulation or something? I'd suggest just wearing warmer clothes to bed and drinking most of your fluids hot. It gets pretty cold where I live and this time of year, I drink almost exclusively tea and hot water. You could also have an underactive thyroid, weight gain and being cold are 2 common symptoms. You can Google the others if you are concerned about that.

I am totaly with you on this one. The more weight I loose the harder it is for me to stay warm. Allthought I do have thyroid issues I blame it on having less insulation on me. start bundling up and drinking some hot tea cuz if your anything like me it is only going to get colder. Good luck hope you stay warm

In the science labs I took in college (many years ago) I found out that Calorie is a unit to measure heat. I often wondered if you ate fewer calories if you would feel colder.
