I have been plagued with these, these are items i've used:
Urva usa - drops work great with water
boil parsley strong put in boillion drink
asparagus, also drink water with boullion
colladial silver, (use only once in a while but works)
Grapefruit Seed Extract drops or caplets don't over use.


Thing's i have heard but not tried
baking soda (be careful check your ph with this)
real lemon water

Antibiotics won't work after a while, so you almost have to try something alternative, there was a formula of drops i used that worked the best had dandelion/urva usa/juniper was called lights of something or another.
