I have had this problem since onset. I have tried many things and am now very regular. However, if I change up my routine, I got constipated for days. My Dr. had me establish a "bowel routine" and it has been working for a good year now. Up to about a year ago strenuous exercise kept me going. I never felt the urge to go unless I was running. I mean never. What I do is eat breakfast every day no matter what within an hour of waking. I wait a half hour and use a glycerin suppository. It is not an "active laxative" per se like Dulcolax. It just brings moisture to your bowels. Anyway, I also pour myself 4 - 16 oz. glasses of water and put them on my desk. It is a requirement that I drink at least that much water during my work day. It screws with me since then I have to pee all the time, but what are you gonna' do? I also take 2 Metamucil capsules 3 times per day w/ at least 8 ox. of water. This has really worked out. If I don't do this to a T, I end up with "rocks" and I can't force myself anymore; there is just never an urge to go naturally.
Establishing this routine has been essential to me staying regular. Constant use of Dulcolax can ruin your bowels; just ask any anorexic. I feel that the key is massive amounts of water during the day. The process is that our waste isn't moving fast enough through our system and we know that as your waste moves through your bowels, it is getting moisture taken from it as part of the natural process. Since ours is slowed down, it takes too much and it becomes hard thus leading to constipation. It's been shitty
, but this is what works for me.
