Ok, here goes....Yes, it can be done without supplements or meds but it will take longer and you absolutely MUST NOT EAT ANY SUGAR OR STARCHES AT ALL!!! No cheese or pickles or vinegar either; no soy sauce too. For salad dressings you may use a little lemon juice in place of vinegar. I make my salad dressing with olive oil, a little lemon, water and greek seasoning. Eat as much meat/fowl/fish as you want. Butter and cream and natural cold pressed oils are fine. I'd stay away from any root veggies at all because even the low carb ones are higher in starch content. No fruit for now, not even tomatoes. Eat a lot of green veggies, especially cruciferous ones, and especially kale. Kale is very high in vitamin C. (I like kale fresh in with my salad greens, instead of shredded cabbage--red kale tastes best) Don't eat iceburg lettuce if you can avoid it as it has the highest sugar content of the lettuces. Leaf lettuces or Romaine/Cos are better. You may have some yogurt with live cultures, but sweeten it with sugar free sweetener and/or add sugar free fruit syrup to it for flavor. If you want a sour cream substitute get a carton of unflavored yogurt and let it sit in the 'fridge for a week, pouring off any liquids that seperate from it during that week. At the end of the week, you'll have a much thicker version of yogurt that substitutes just fine for sour cream.
Basically, you are not to eat anything that will encourage the little beggars to continue to live or multiply. The yogurt will help you replenish the beneficial bacteria in your gut which will compete with the candida for nutrients. Eating yogurt every day for at least the first two weeks will help a lot. If you need to lose weight, it'll probably drop off very nicely. If you don't need to lose, you probably won't as long as you eat plenty of food. Don't try to starve yourself, it'll only make the die-off symptoms worse. Be prepared for the die-off symptoms. Lethargy, headaches, muscle aches, cramps, flatulence, light headedness, funny smelling breath/armpits, embarrassing itching....
Pamper yourself during this time. Take luxurious baths for the odors and use zinc oxide powder for itching. Take lots of naps whenever you feel yucky or headachy. Give it at least 3 months for most of the symptoms to start easing up. It may take up to a year to kill it off entirely. Please don't let that discourage you because once they're gone, they're gone. Think of yourself as an exorcist getting rid of a demon!
They're quite stubborn and as they die off you will get the most INTENSE cravings for sugar/starch/fermented products. If it gets really bad, then just stuff yourself full of something fatty like steak smothered in butter until you couldn't possibly eat another thing. It'll get better as time goes by.
