I had severe constipation for 3 weeks and all that would work was strong OTC laxatives. Then I saw a doctor and followed these instructions that worked. Start taking Metamucil 3 times a day plus 2 proactive pills. Also for only 3 days take one dose al day of Miralax. Also drink lots of water. I added 1 glass of prune juice at night along with papaya for dessert. I ate oatmeal, bran cereal, and salad with beans for lunch. And chili with beans for dinner. First 3 days were ok. After that I was cured. I am going to keep a high fiber diet and eat less breads and less dairy.
