Before this pregnancy, I was drinking warm lemon water every morning for many reasons, but one of the benefits was that it kept things very regular (easily). I would put a kettle of water on the stove, then cut a lemon in half and use a lemon squeezer to put the juice into a glass, fill the glass a little more than half full (so about 6 oz?) and when the water was boiling, add about an inch of water to the top if off. Then drink it down and wait at least 15 minutes before eating, drinking or doing anything else.
Unlike some, I did not use cayenne pepper in it, just the lemon and water. According to a friend of the family who is a nutritionist and currently in a naturopathic medical school, this is supposed to be good for just about every organ. It cleans your liver and kidneys and also cleans out the digestive track, safely. But, good luck getting me to do that until the nausea subsides. I'm afraid of what would happen at the moment.
