Yup, the doctors know f***-all. Seriously. When I asked about Candida I had 4 doctors tell me it wasn't real (even though my father had already been successfully treated for it). When they can't find out what's wrong with you they want to send you to a shrink.
parasite cleanses are the #1 thing anyone with Candida should try imo, along with diet changes. Do a Barefoot (the best) or a Humaworm parasite cleanse. It's where I started and it gave me enough energy and hope to continue to learn more.
