Hi Nutragrl,
This isn't actually Jeff Novick's part of the forum, but you can ask him directly in the section under his name in "Connect".
I just wanted to add a few comments to what the others have said. The beauty of the McDougall plan is it's simplicity. There is no list of "must-have" supplements, no schedule for eating, no list of super-foods, nothing you need to buy other than basic food from any ordinary grocery.
It's just a matter of choosing some starches that you enjoy and planning your meals around those Optionally, add smaller amounts of whatever vegetables, fruits or seasonings you are able to digest, and give it a little time to see if you are feeling better.
That's really it. Pick a starch and focus on that whenever you are hungry.
It's the food!
My experience only with probiotics was that they gave me diarrhea and cost a lot money.
Sadly one of things most doctors/ dieticians/other healthcare practitioners can't tell you, because they don't receive training in this, is that gut bacteria can take a long time to recover from antibiotics.
They may just dismiss your issues with a simplistic "eat some fiber, go take a probiotic (and please go away). But that won't help the problem. I haven't encountered any doctors in real life who are willing to discuss antibiotic after-effects or side-effects.
There is mixed evidence for the effectiveness of probiotics, but you may have to dig through scientific papers to find out more. If the results of probiotics aren't what you hoped for, that's not abnormal. It may be better to try a simply food-based approach instead and see what happens.
Your microbiome is not like any other and what works for me might not work for you. So you have to literally trust your gut to tell you what works for you/it.
You will get there, but be ready for some trial and error on the way.
Best wishes!
