What Causes White Coat On The Tongue With Tingling Sensation?

After taking 8 rounds of antibiotics during a period of a year and a half I started to develop symptoms that I found on alternative care sights describing systematic candida. After wearing the same size for over 10 years I gained 2 dress sizes in less then a year, I had oral thrush, 2 yeast infections, foggy brain and an increase in mucous. My husband also got thrush and a penile infection; i believe he caught from me. We both went on that crazy anti-candida diet, took grapefruit seed extract, oregano oil and garlic and took probiotics for 3 months. Most of our symptoms have cleared. However, my tongue still has a thin white coat every morning and evening that brushes off easily, the tip of my tongue has a tingling/burning sensation and I see increased mucous when I eat things with surgar such as soda and wheat such as bread with gluten. In your opinion have I treated my candida? What could be the cause of lingering symptoms?
