i was on diflucan for 4 weeks once a day and my nugget the same time for 2 weeks and it finally killed it. i would try to get you both on it at the same time, and then rather than take 2 a day, take it for a long period of time.
i agree with the earlier post, that i didn't notice a change until after a week, at least.
i also got great advice from my midwife to take acidophilus 3 x a day, plus 1/2 tsp of collodial silver. we also threw out the paci and only gave a bottle once a day (and sterilized for 20 minutes in boiling water after use, plus applied nystatin cream to the nipple after boiling). also, i stopped using nursing pads entirely. this was super hard because i leak all the time, but i just wouldn't nurse in public and when nursing, would open both sides and let my other side drip into a burp rag while she fed. i would wash my boobs after each feeding, no washcloth, just toss water on it. and i started sleeping topless.
thrush is so horrible. hang in there!
