Is this hypoglycemia or sugar intolerance?

I eat very little refined sugars--mostly just honey. I eat veggies, rice, meat--all healthy. Anytime I eat more than one or two cookies sweetened with brown sugar, or a little too much honey (really not excessive amounts) in the evening, I get pulsations in my stomache, twitching muscles, have difficulty sleeping, and wake up with sore muscles, bloating, and a foggy feeling as if I haven't slept that stays with me all day--along with excessive hunger and/or an inability to eat much without getting bloated or having sympotoms recur. interesting, eh? I also have hypoglycemic symptoms from time to time, am hypothyroid with other food intolerances (milk, wheat, etc.) and underweight. 27 yr old female in distress.
