Re: serious bottom trouble here
This sounds typical of IBS, I have IBS myself and can go to the toilet two or three times within a couple of hours in the morning and then cannot go any more all day and feel absolutely bloated. It really is the most nasty condition.
Have you had a Colonoscopy because you really need to find out what the problem is and not just guess work.
Colonoscopy showed I had Diverticulitis when I had bowel problems and also IBS.
I hope you get it checked out for your own peace of mind. Good luck,
