This is strange.
Let me explain my job first...
I'm a photographer. And right now, we take pictures of tourists that are taking a boat out to a fort on a island. We shoot every boat (3 boats at one location and another 3 at another location). The boat is gone for 2 hours 15 minutes while we edit all the pictures. Then we sale them and do the whole thing all over again. We also have a night shift, were we take pictures for people going on a fancy dinner cruise...they are gone for 3 hrs and 30 minutes.
So here's my little strange thing. I usually only work nights (5:30pm-11pm), and one to two daytime shifts (8am-4 or 5pm). I work fine at the night shifts with no problems. But when I have to work during the day i start feeling like i have to go to the bathroom, so i try to go before i go to work...i end up going like 3 times before i leave the house and still have the urge when i get to work! A couple times i actually was at work and ended up have explosive D at work! So I started taking only one immodium before my day time shifts. It really helps too! But Im looking into another photographer job that would be 8am-5pm M-F. I can't take immodium EVERYDAY. That's why I have started metamucil, hoping it will regulate me.
I'm thinking it's a pyschological thing. "oh man, what if i have an accident?! I think I gotta go! This is so embarassing, i have to lie and say i have to throw up, i can't tell people i got to take a bad crap!" haha It may also be that by the time i have to work at night, i have already gone to bathroom and got most of it out. Cause I ALWAYS feel full. I have yet to feel like i don't have to go since i have had IBS. And my doctor knows this, but he says not to worry.
I really can't wait till they know more about
