I am having similar symptoms, but I wasn't sure if it was necessarily tied to carbs. At first I thought it was tied to caffeine, so I gave up caffeine. I am hungry all the time, and it just seemed that I was nauseated after eating. I had two episodes where I was extremely nauseated, dizzy, and numbish. I would also seem to get overheated very easily, or if I was hot it would make me more uncomfortable. I'm only 30 so I don't think I'm going through menopause. I went to the endocrinologist and he didn't find anything wrong. Blood sugar readings and TSH were normal. I still don't know what's going on.
