It sounds like you need a new bag. But for future considerations I find it helps to sleep with a thin merino layer on and sleep with the bag unzipped rather than sleep in your ginch with the bag fully zipped. Bare skin against the thin synthetic bag material tends to cause sweat no matter what the fill is. That coupled with with eating 500% of your recommended sodium every day in those Mounatin House meals causes your body to do some strange things.
