I sometimes forget when I have showered and when I have not. However, within the last week I have showered 4 times and only brushed my teeth in the morning. I have to start brushing twice per day where I am using aa special toothpaste for my nighttime brushing. It is really hard when you see showering or even bathing as a chore. That's the way it feels to me. I often wonder if it would be o.k. just to shower every other day and get away with it.
