I've dealt with this ALL my life,......until someone recommended Prunelax. It has been working great for me! I have a tortuous intestine. I'm 70 years old. I've suffered my entire life with constipation. I have way more intestine than I should for a person my size. I lived with it and took Bisacodyl off and on. The Prunlax is much gentler on the system and much more controllable than the chemicals. I did find that I need to take either 4 mini tabs, or 2 1/2 of the PruneMax. This keeps me going and my gastro Dr. has given her approval of this regimen. I take it every night around 7:30pm and have bowel movements the next morning. NEVER in my life has this happened. The Prunelax will change the color of the intestine but it is harmless. That's due to the senna. I hope this helps,............someone on this site gave me this info almost a year ago. I am so grateful. And you're right, the doctors give standard answers and don't treat the individual. That has been my experience for many many years. Jacque
