This formula is specifically for controlling or overcoming bed-wetting and strengthening the entire urethral canal, kidneys, bladder, etc. Another helpful hint prior to retiring is to fasten a ball about six to eight inches in diameter of yarn or string or cloth onto the nightclothes in the middle of the back. The main reason for doing this is really quite simple; it is helpful in preventing the individual from lying on the back. Why? When someone lies on their back, this is generally the time and position in which the valves release to void urine. How does this work? Well, when this person rolls over onto their back their tendency is to start to release urine. However, due to this incredibly uncomfortable ball in the middle of the back, they tend to wake up just prior to voiding urine, thus, saving much clean up time and mess, not to mention all of the embarrassment that one would experience if this were to happen.
