Does anyone have any suggestions for chronic constipation?

I’ve tried probiotics, I’ve tried laxatives, and I’ve tried stool softeners. It hardly helps. I’m really concerned about the negative effects of excessive laxative use and the possibility of abuse. My stomach is just so hard and gurgling all the time. And it often hurts.

I exercise at least 30 minutes every day and I drink as much water as I can handle, like 3-4 bottles.

I don’t know what else to try...
