I want to stop taking míralax

I have been taking miralax for 6 months now. I stopped for one week and when I went to the restroom it was very difficult to get the stool out. I even considered going to the ER. I’m back on miralax but I refuse to believe that there’s not a natural way to manage constipation.

I don’t take any fiber supplements because those increase the size of the stool and can result in hemorrhoids or fissures. (Happened to me)

Any ideas?
