I think its possible for it to be sexually transmitted. me and my partner have passed it back and forth for 3 years.
you will feel terrible because the balance in your body is out. until you get it back you will have these symptoms. you are on the right path so dont despair, the fact you say you have just finished some antibiotics means they have probably wiped out the remaining good bacteria that where keeping you on a par. the same thing happened to me.
keep on with the diet and try to be patient because sadly its not going to right itself overnight.
I havent found a doctor yet that believes candida overgrowth is possible in previously healthy people, not unless they have cancer or HIV> I lost faith in the medical profession last year.
I also was ill for the first 6 weeks of the diet before i started to feel it working so dont despair. you will be on the road to good health
