Help..terrible smelling gas when eat carbs...WHY???

Hi
I was wondering if you might have a little bit of knowledge about what is going on in my gut. I can't figure it out.

For a few years now, whenever I eat carbs like white flour or wheat(not sugar..candy)....I get terrible , painful gas that has a terrible odor.

I can't fiure out what is causing this odor.

I started the Colonix program 2 months ago and from day one I got out MP. Sometimes 4-5 pieces a day. Everyday it comes out!!

The only time I can control the gas/smell is when I take those carb blocker pills....made from Kidney Bean extract. They are supposed to hinder digestion of carbs. Well, I get no gas and no smell.

So this week it has been terrible. The waste coming out has the smell of the gas. An almost sulfur smell.

Do I have a parasite problem or an allergy to wheat? Is this what Candida is?

Thanks so much for your time and knowledge.
