Hi Ellen! The New West diet is one of the articles on that Doctor Within site I gave you. (it's interesting isn't it?!)
It might be best for you to start by changing your diet and see if you can't eliminate the gas and bloating that way first. I have thought about the position you're in and talked to a friend and it just might be difficult for you to Bowel Cleanse if you can only go once a day. It's a tough one. But much could be improved by eliminating certain foods or food combinations that cause you gas. Maybe you could keep a journal re: what you eat and what gives you gas and you'll be able to see what affects you. The New West Diet encourages lots of raw foods....and eliminates sugar, wheat and dairy basically. (unless you can get some unpasteurized cheese for occasional use!)
And did you read the basics on food combining? No protein with starch? ....and other stuff too.
I think you might have great luck with just a change of diet. I hope so!
