Was it a right decision to stop the antibiotic???

I know that D can develop while on antibiotics or after finishing an antibiotic course. But the purpose of giving me this antibiotic was to treat D. I'm on Rifaximin (Xifaxan) which aims at treating Crohn's. I started this med a week ago and things were going on well and I had only one or 2 bms per day. However, yesterday, D returned again 6 times and then I took Lomotil but it was not effective. Today, it is the same add up I'm vomiting and have cramps. So, I decided to cut this med off. But I'm confused. I'm tapering pred 5 mg as I'm waiting for Entocort 6mg to kick in and my doc told me to try to eat and I'm afraid that I ate eggs and it might have caused this D. Was it a right decision to stop the antibiotic?
Your replies are highly appreciated.

Thank you, Kazbern. Well, my doc did not mention then the reason for prescribing Xifaxan. I became better though I have to take Imodium but the cramps have gone away. I won't resume the antibiotic and yes, I ate yogurt and I don't know whether is it that improved the symptoms or not. This disease proves everyday for me that I don't understand anything about it.
Take care!
