Thanks for posting- I'm having similar issues. I'm a 33 year-old female in my second year of medical school, and about eight lbs overweight according to the BMI scale. When I stay up late studying I crave (and eat) sugar. I have been a sugar addict for as long as I can remember, but I know it's not good for me so I try to control my intake. The numbness in my hands and arms while I sleep started probably a couple of years ago. I have never correlated it with my sugar intake, but I've also never thought about their possible connection. I'm going to stop eating sugar and see if my symptoms subside.
I have had similar problems. I went on the Daniel fast for 21 days for other reasons but during it which includes No sugar The problem went away. My cholesterol also went down 31 points. I really only missed cheese. I am thinking of doing a modified one with no sugar or red meats.
