Your D journal isn't sad! Lol! I mark the # and quality of BMs I have on my calendar as well as in my food journal! The food journal has been a great help; I've been able to pinpoint some things I never would have thought of such as the soy substitutions for dairy that contain casein and the sourdough bread (although I admit when it comes to bread I can overdo it, which would probably make anyone sick).
There might be some studies posted in the IBS Research Library about the birth control pill and IBS. I know for some people the Pill has made their IBS worse. However, in my experience, the Pill has actually helped; I've been on it for about eight years now. I did go off it for about a year and during that time my IBS worsened--especially the week before and during my period. I did have to experiment with a few different pills before finding one that reduced my cramps and duration of my period. Because my periods are shorter and the cramps minimal, I find I rarely ever have a D attack during that time. I still get period farts, if you know what I mean! Lol!
If your attacks happen at night, why not try taking 1 Immodium before you go to bed or following dinner? At least this way you can get some rest and break that cycle! Speaking of breaking the cycle, here's a link to Heather's recommendations I think you asked for earlier: FAQs (including BTC overview) and What to Eat When You Can't Eat Anything (I hope this is the right info you wanted).
