You have a great attitude. Don't worry, I'm sure you don't have a 15' monster, maybe 15" though, but they pass silently like the little ones :).
Personally I have to take more garlic than that, if you took more it might speed things up, but you will smell worse. Its just one of those things you have to determine by how you feel and the progress you are making.
Having these things is definitely something you don't think you could have until you have them....it is a very humbling experience.
