I haven’t tested myself after eating in the morning so I don’t know. Yes I always wake up the middle of the night usually to go to the loo. But when it’s really bad, i.e. super high cortisol I think, I wake up with all this pent up energy and a compulsion to run in place, etc. I eat the bulk of my food in the evening and have a bedtime snack of oatmeal and low carb homemade ice cream.
