Actually, you haven't been doing very much yet! Sorry, but taking pills doesn't count much when it comes to candida. I wish more people knew that, sigh. Ant-fungals is only 10% of the total cure.
Undigested pills indicates that your problem with candida is caused by too little gastric juices in your stomach and too few digestive enzymes and not enough bile rpoduction. You simply are not digesting your foods into a paste, and that means that microbes have to finish the process like leftovers in a fridge. Don't blame them for doing their job, which is keeping you alive most of the time! :)
Please read the FAQ on this page - power of digestion first, then candida notes. The main thing you have to do is increase the power of digestion and cleanse the bowels of all old fecal matter. Starting out with an oxygen-based cleanser is a great way to begin, but ifyou're suffering from massive brain fog (read the post on healing crisis and brain fog) then you need to get your own enema bag setup so you can do coffee enemas and empty your liver of toxins very quickly.
You also need to be cleansing your lymphs - see the Lymph Cleansing post in the FAQ and do as many of those options as possible. And read the post on Leaky Gut too, that's a major cause of brainfog.
