Hi Deb! I was just wondering about
you the other day.
I am not sure why this is...but I am the same way. At times I can function fine 'on empty' until it's time to eat...
...and other times huger can shut me down!
There are probably a lot of factors, but the important thing is just to monitor your body's signals, and take care of it at the first sign of an issue.
How have you been otherwise? Well I hope!
S.C.
