Waterpik resulted in immediate regrowth within two days. Gargle antibiotics were worthless. Internal antibiotics were effective for about three months before another regimen became necessary (and that's not good for MANY reasons, the least of which is the problem at hand).

Plus, now maybe my wife will stop bitching about the stank.
