Go to a naturopathic doctor; I highly recommend it. They will prescribe you healthier versions of many of the supplements mentioned here on the forums (from trusted brands, cellulose free, etc) and you will get healthier in weeks vs. months. Naturopaths prescribe some homeopathic remedies which will get your body to naturally bring itself back to normal.
Nutritionist just tell you what to eat if your diet is already poor. I think you have a good idea what to eat with the candida diet at this point.
