A friend of mine started "blowing air into water with an straw" (making bubbles) very seriously. I was very skeptical to say the least; but after a couple of months the effects have been very eye opening. Not only it has helped sleep apnea and snoring but also helped with reducing their weight. They had an online group and most participants reported the same. The wight loss was reverted when they stopped for some personal reasons. I wonder if making bubbles in the water has the same effect.
