I agree with Jhan, sounds like you have some liver congestion. Tums contains sugar, which may have aggravated/caused the candida, but it was the liver congestion that was behind it all the time. If the liver is congested with stones, then the bile and bicarbonate (secretions made in response to food that is dropped into the intestines from the stomach...these neutralize your food and balance intestinal pH) are not being secreted enough, meaning that your intestines are now an acidic environment (friendly towards candida). The Sugar in Tums probably didn't help that any. I would suggest stopping the Tums and maybe doing Hulda Clark e's liver flush. That "cured" my candida problems.
Anyways, good luck! :)
