Thank You. For The Past 3 Months, I Have Experienced

Thank you. For the past 3 months, I have experienced a change in my stool. Although I battle constipation for years, I generally have a solid bowel. Three months ago, it turned to pebble-like stools, with constipation. I eat a wonderful diet - lots of fruit and veggies, and drink plenty of water. No caffeine, no alcohol. When I have a bowel movement, it can be as many as 10 or more of these pebbles - sometimes slightly larger pieces, but rarely a normal size.
