I totally understand, and can relate to the constipation all your life. I only found out about my tortuous colon when I had a barium enema. But NO guidance from any Dr. and that was 11 yrs ago. Senna is natural but any stimulant laxative can become a habit and possibly lose it's ability to do it's job over time. I'm back on Miralax and had to take milk of Mag. last night. One thing I did do was got" squatty potty stool" It helped so much this am. I'm certain any stool that elevates your legs will have the same effect. I realize though for years I never drank enough water. As a kid I never drank water only milk, which added to the constipation. Redundant colon and the extra time it takes for food to transit our bodies is so very stressful. I have been making myself walk more and move more. I used to dance before the Pandemic!
