I stopped eating low carb in December, and since then have been pretty high cal apart from a short period of restriction at the end of Feb. I've had an ED for about 13 years though.
1) Don't sleep with mouth open (as far as I know)
2) Brand new thermometer
3) Warmed it up for about a minute before using.
4) Seem to have some of the symptoms Getting my bloods done next week.
I checked my temp last night and it was about the same... but I didn't pay much attention cos' I thought I might just be cold.
