Hi! Welcome. What your coach says makes sense. I was bulimic in my teens and twenties. Looking back, I also believe it was candida driven. There was just no way to stop eating carbs and sweets, and then I would be so full I would feel sick and need to purge. And of course the cycle would start all over again. I have been meaning to do a poll here to see how many candida sufferers once had bulimia, or even still do.
To start, best is to READ READ READ! Check out the recommended posts at the top of the page. The diet is a must. There are many versions, but basic first step is to eliminate all sugar, dairy and flour products. Make sure to get plenty of veggies. I also believe in getting good quality protein at every meal, but others will differ on that point. Eliminate anything processed for sure. If you do a web search, you will get a few versions. Pick one and go for it. There are a lot of supplements out there that can be helpful. If you read and see what others who have symptoms similar to yours are taking, you might want to try them as well. Make sure your detox pathways are open so that candida waste can be eliminated when you begin to re-balance. That means enemas or colonics if necessary - you do not want to get constipated and should "go" at least once a day, preferably more often. If you begin feeling lousy, tha is die off, and yuo may want to consider some liver support as the liver often gets stressed during a candida detox. Good stuff for the liver include silymarin, Livatone Plus, LiverAID, NAC, chlorella. Also, keep a food journal. Clearing candida often reveals food allergies , and you want to eliminate any foods that are cuasing you troubel, as they further stress the liver.
Since the subject of healiong candida is so broad, and not everything works for everyone, it is often helpful to get a little bit of this under your belt, and then you will have more specific questions which are easier to answer.
