I have had trouble with constipation all my life. I can remember having my first enema at age 5 and castor oil every night. I have tried numerous types of fiber products and they make matters worse and also cause bloating and trapped gas (yes, I drink plenty of water). As a result of my chronic constipation, I have horrific hemorrhoids. I cannot let myself get constipated or the hemorrhoid pain is unbearable. What works for me is magnesium citrate. I take it every night in capsule form. I take anywhere from 800 to 1600 mg. depending on how plugged up I am. My gastroenterologist said it was fine to take every day.
