If in fact you do have for sure an overgrowth of Candida you must first really clean up your diet and your health. You must be familiar with the diet, right? Get on it if you are not on it and stay on it. This is number one. The diet probably will not cure you but will make your road to recovery smoother and your body stronger and stronger. Some excerice would really help also like walking or when you are stronger the Yoga Sun Salutations in the morning after your shower will help keep the system open. You gotta do the diet and the way things sound you should not be thinking in terms of building up, but in terms of settling things down. I do not know where your head and habits are, but one other thing would be good and that is not to eat in between meals. Go with the veggies and go easy. Relax. Next if you are treating yourself you gotta use a little more common sense and slow down. With the Grapefruit seed extract, if in fact you wanna keep using it at this point, move down to one drop per gallon of water and see how that works, or move to another antifungual that will not be so harsh on your system right now. Caprylic acid might be good to start with and then after some days on that move to Thorne's formula SF 722. There are all sorts of things to do. You can learn a great deal from this list and other sights on the Net. Things may take time, but probably everything you do in the name of curing yourself will help in some way.
