I usually use it once a week. If I have a cold, then daily until the chest crap breaks.

Last year I only had 1 cold and it wasn't bad. I think I used it for 4 days straight. Chest crap broke up and went back to once a week.

Remember its only a shot right. So 1 oz.

I usually start at the beginning of the fall which is one of my bad times, until the sun shines for longer than 5 hours in the spring and the temperature has been high enough to get rid of the dampness of winter.

Hope it helps.
