My vote would be candida. Check out the Candida Forum . If you are eating Sugar and lots of carbs, you will need to eliminate them and begin Phase I of the anti-candida diet. You will have to stick with the diet because it is a slow process getting your stomach and bowel flora back in balance.
Are you eliminating well? Liver Flushing is good but if you are not eliminating well, you can bee pulling toxins out that then get stuck in your bowels. I would suggest trying some psyllium/bentonite and caprylic acid shakes for a month or two or some other type of bowel cleansing or a combination of both.
