Tongue Question

For those of you who had a white or yellow tongue and are on the candida diet, how long was it before your tongure started to go back to a pink color? I haven't seen this yet and its been about 3 weeks on the diet. My tongue actually looks a little yellowish which is starting to freak me out. I wonder if my liver is taking on too much? All I am doing is diet and garlic every so often. What do you guys think?
