You could try stopping the gin on your cornflakes.

Seriously though, that is the flippant excuse I use when I am like that. Temperature increase will do me in everytime - so will fatigue and getting up during the night, oh, and getting out of the car after a longish trip...walking too long or too fast....the list goes on.

Sorry you are feeling so bad. I am just wanting you to know that I get it.

Hugs

Lyn
