Some of your symptoms do sound like they can be IBS, however, it also sounds like some sort of imbalance. If you haven't had any tests yet you might want to consider getting your Thyroid test. Consider seeing an Endocrinologist and get your homones checked (along with the thyroid).
It seems that most IBSers can't handle too many sweets in abundance or too frequently. It's good that your doc wants to be thorough and scope you, but most docs do the other routine tests first... blood, stool, ultrasound.
