You're going to want to significantly change your diet. Look up an anti inflammatory diets; dairy and gluten (wheat, yeast, etc.) should be cut completely from your diet. Do the same with sugar (not considering sugar from fruits, but that's really it). Yeast feeds on sugar; it is now your mortal enemy. Consider getting food allergy testing done. Costs around 100$ but is paramount in safely structuring your food choices.

Start taking a probiotic, twice a day (once morning, once at night), and at least half an hour before food.

Please look into Coconut Oil; it is now your best friend. Google coconut oil and candida for more information. Coconut oil will absolutely help you with candida, taken (both) orally and applied topically.

Protip: if you're taking curcumin for your TBI, you can heat milk (or almond milk) in a pot until boiling, turn the heat down and add a teaspoon of coconut oil, cut open and add a fish oil gel, add 1-2g curcumin, and stir for 3 minutes. Curcumin is not bioavailable orally, unless paired with piperine, or dissolved in a fat or oil. This process makes curcumin bioavailable, and gives you an oral dose of coconut oil.

All the best.
