Nancy, I did tons of expensive probiotics and yogurts for over a year, and they did no good at all.... I tapered off them finally, and noticed no difference being off them. I actually did two "transplants" right after my last round of Metronidazole, by the book, and they didn't seem to have any effect either... Tests showed that the C. diff was gone, but what was left of my gut bacteria was way different than what I'd had before.
I eat no gluten, raw veggies, soy etc., just alot of meat, eggs, cheese, a small amount of white rice and potato (from the garden!) and some cooked veggies. I've chopped out all the big categories like dairy to no effect.
The only thing that has helped is TIME. I think maybe my exposure to different bacteria just as a course of life has slowly recolonized my system with some better bacteria, but the IBS symptoms may never go away totally. I'm like a little old lady constantly monitoring my bowel functions; a few weeks ago I was so proud I almost took a picture of it!
I still have lots of gas in the mornings, and some bloating, but for the last six months, I almost never have diarrhea UNLESS I went VLC the day before. Two days ago I didn't even think; I had LC tacos (meat, cheese, sour cream, sauce, lettuce and tomato) for BF and dinner, no other meals, and the next morning it just ran out of me. We have tacos all the time, and they never bother me, just usually I have other stuff also during the day.
I've researched and experimented with LC for years now, and this has really got me baffled and depressed. My next step is to break down and call the doc for a colonoscopy to make sure nothing more sinister is going on. Yuck.
Note to everyone: Make sure you REALLY REALLY REALLY need antibiotics before you take them!!! THIS is what can happen.
