Prior to December 2010, I drank 1 - 1.5 cups of fat
free skim
milk for breakfast every day, for years and years. However, in December 2010, I had stomach flu for a few days, and a primary-care doctor told me to stop drinking milk until the stomach flu went away. Three weeks later, after the stomach flu had been gone for about 2 weeks or so, I tried drinking milk, and I had an upset stomach. So, I stopped drinking milk once again, and I haven't had any milk since then.
