I agree with Belinda. If you really want to feel better and get control of your IBS you need to change your focus from body building to following the EFI diet.
If you have Heather's book I would suggest re-reading it to learn the concept of the EFI diet and why it works. Do this without thinking about body building and trying to get so much protein in your diet. If you don't have her book there is so much info on this site that you can use.
Many of us are telling you the same thing. Hopefully you will listen to the advice you are being given and concentrate on getting well before body building. You really have to look at your priorities and what is more important to you. If you are not ready to make a real change in your diet there is nothing any of us here can do for you.
