Its not always easy to diagnose what you have as these symptoms could be for something else. I would however suggest you do have candida. Do you bloat or have symptoms after eating mold (orange juice, peanuts, wine) or sugary foods? If you do you are likely to have candida. See if you can find a naturopath or nutrition specialised doctor in your area and get diagnosed properly - if diagnosis is important. Otherwise read up on this forum and diagnose yourself (I did and then had it confirmed).
This is the best place to learn about how to fix the candida. Read Shelleycats post in her forum for the best advice.
Another thing too is with the weight loss being a problem I would recommend you doing an allergy test from a naturopath or doctor. Years ago I found out I was allergic to yeast so stopped eating bread and within about 1-2 months had lost over 10 kilos just because I stopped eating bread. I was still eating normally otherwise and it was like my weight just stabilised to where it thought it should be. Now I seem to lose weight very easily where once no matter what I did it wouldnt come off.
