Ducolax made me sick. It made my mouth taste like metal, then I threw up.
Not to be too graphic, but not everyone one goes everyday. It all depends on your lifestyle, active or sendentary, what you eat, medication, supplements,stress level, etc.
When you do go, the perfect stool, floats, no joke. If it doesn't then you adjust your life until it does.
If you are constipted and take fiber you could get backed up and get impacted. That is not a good thing. You have to watch when and why you take fiber. If you feel that you are not going because you have hard stool, then you need a stool softener until you can adjust your diet and lifestyle.
Fiber is for instances when you don't eat a well balanced diet, you are not active, constipation from meds, etc.
If I were you I would opt for a stool softener, and then eat more fiber and be more active. Fruits and veggies.
Laxitatives are over rated. You can do the same thing with food and LOTS of water.
If you really feel that you are backed up go buy some stool softener. That will help in the end
