Since you've already explained the main source of the odor, can't I just Google how to fix it?
Absolutely.
In fact, I encourage you to compare my explanation with other sources before deciding whether my guide is right for you.
Once I had identified the main source of the problem, I realized there were a few factors that contributed to that source. I Googled it to no end and was expecting to find a complete explanation of those sources and how to address them. Instead, I found information discussing some of the individual pieces of the "puzzle," but I never found a single resource that brought everything together, completed the puzzle, and then created a guide for others to complete the puzzle themselves.
Simply cleaning the source area wasn't enough. I needed to figure out why the material was becoming trapped and stagnating in the first place and how to reduce that trapping over time.
The Breath Guide is the result of decades of living with this problem and years of trial and error after I reached that conclusion. The guide explains the complete daily routine I developed, how to properly clean the area, the facial and jaw exercise I use to help keep that area more open so material is less likely to become trapped again, and how the routine changes as the problem comes under control.
In other words, knowing where the odor is coming from and knowing how to consistently control it are two very different things.
