I wish I could give you GREAT advice. Although not knowing I have suffered from Candida for 10 yrs I am just on my third go around of trial and error to get rid of it. Is that ever possible? Some say yes.
I feel for you as my daughter is in college and your age so I know its hard. I believe she has Candida issues as well but doesnt want to acknowledge them. At least you are.
Try your best with the diet and make sure to stay faithful with the probiotics and anti fungals.
I am way older then you and I slip and cheat on the diet too. Its hard and expensive for me. Hang in there. I hope things get better.
