Hey, you guys can laugh all you want but a sage voice at the meeting told me that it really does work! The question is that there is no long term directions on the bottle or website for use...... It tells you about one application followed by a vague reference that if nitrates are really bad you can double the dose in the future, but not how often to use it. From the way the instructions are written you get the feeling that it's used regularly but not how often. The website just repeats the label. Anyone know?
