Fasting is discussed in the Bible near 40 times. I'm aware that it is of value for me to fast near the equinox, spring, summer, fall, and winter. I usually fast for a day or two for each of those times. This year I came down with a deep cold that prompted me to begin a liquid diet. I used Green Tea with honey and Ginseng diluted with natural spring water and two Emergen-C Raspberry flavor added. I maintained that cleansing process for 14 days. It was a very useful method to stay well while cleaning out the accumulated gunky yellow, green, white and clear mucus. It was a bit inconvenient but I avoided people, no kissing and little touching.
I am renewed and strong probably for another year. During my fast I decided that I am going to become very particular about my vegetarian/vegan diet by choosing less bread and fewer desserts...fluff foods, unnecessary, just fun.
I was forced to fast although it is more convenient to not be forced. I have decades of experience with fasting and realize that usually a health care adviser might be advisable...chiropractor, coach, DO, MD or other health consultant/guide. Be Well, God Bless
