If you have been doing it for weeks then your fine to add another one in, if your not having bad die off. I also take coconut oil, but never without any other anti-fungals, you need to do a rotation of a different antifungal every four days, candida is very strong and gets use to a anti-fungal fast if not rotated!! I use coconut oil every day (since I don't feel it is as strong as the other ones)and rotate the other antifungals every four days.
I started twith two tablespoons a day and didn't get much die off with it, even starting at that high, so think you should be fine, if not then just go back to two and work up slower :)
