Usually, you want to take the fiber with a meal. Most people take the fiber in the morning with breakfast. You always want to make sure you take at least a full glass of water with the fiber, in any form.
Maybe you would do better with a high fiber cereal such as Allbran or Fiber One? It is excellent when made into recipes.
There is a recipe site called:
It is a site for those who want to lose weight, eat healthier, but yet get good tasting food. She revamps recipes, and she is always using FiberOne cereal in her recipes. I have tried many of them, and they are GOOD! You get daily emails, but you can archive for recipes and ways to use Fiber One, such as oven fried chicken, etc.
Maybe, also, a stool softener might help. You can take it up to twice a day. Many people do.
If you do increase fiber, just do it by a couple grams a week. You don't want to risk bloating and gas. Give your body a chance to adjust.
Please let me know if you have any further questions or concerns!
Fiber recommendations for men under 50 is 38 grams, and 30 grams for those over 50.
