Have you gone to the doctor to get a diagnosis? That should help you decide which treatment plan is best for you. What types of foods do you customarily eat? Are you presently taking any supplements or vitamins?
You say that you suffer from bad breath and candida (white toungue, sticky salivia and vaginal thrush), so why don't you read what hadenuff29 wrote about what helped his symptoms under http://beatleakygas.com/
Also, his posting subject: I'm 100% cured of fecal odour/leakygas explains it pretty well.
My nephew got mouth thrush from having a respirator tube for a couple of days, and the doctor put him on some medication for it. I think the infection was going down his throat and into his lungs as well. I don't know what medication it was, but I highly recommend that you see your doctor to see what he/she says.
