I'm wondering if you have thought about keeping a life journal and a food journal. Sometimes, when one writes out things and then looks at them later, one can start to see a pattern of triggers.
Next, the food journal would help you be aware of what you have eaten that day as to carb count.
Are your foods correct? NO SUGAR, no flours. What vit-nutrient supplements are you taking?
Have you had any blood work done to check your glucose, your blood lipids, a general chem panel?
