10 drops are not enough and the liquid can loose it potency. try the capsules. I dont even remember how long I been taking them its been maybe 2 years. and yes fungus or candida do mutate and can be resistant to H202 at times, thats the reason why the supplements I recommend are multiple products
If you dont feel like taking all that I recommend, then at least take these 3 below
zero2sixty
caprylic acid ( I take nowfood brand )
Kolorex (I take swanson brand )
