Re: 5 year challenge - need guidance
Flat stools are usually caused by not intaking enough soluble fiber in your diet.
Psyllium seed husk is a water soluble fiber and a bulking agent that not only will bulk up your stool making it more tubulalar shaped and also makes you more regular. It's a natrual and safe fiber that I have taken twice daily for the last 23 years--- It works for me!!
I wrote a post on the "Information Archive" thread at the top of the page about Normal BMs -- post # 10 on page 2. It's about the differences in fiber--- You may want to read it.
I wish you well---Harry
