Hi BKelly and welcome!
I'm not that familiar with night sweats. I know they can occur in menopause, but so far, I've dodged that bullet! Just did a quick search on 'night sweats' and many things came up: various medications, infections, medical conditions, etc., so that's probably not a lot of help. Seems to be 'all over the map.'
Sugar does bizarre things to my body. I can tell it kicks up my nervous system at times and makes it go wacky. It's probably entirely possible that it could cause something like night sweats, but it may be best to check with your doctor to see what exactly is going on, and rule out other conditions.
Have you checked out Fibro 101, the very first post on this forum? There's some great info.
Hope you get some answers soon. Keep posting. Wish you the best!
