I'm glad to hear that you've been checked and cleared of blood sugar issues.

Something you can check is whether the carbs you're intaking are quick-burning simple carbohydrates or slower-burning complex carbs.

You can also check to see if you are gluten-intolerant.

Really, there are a lot of issues that this could be a part of.
