Probiotic Dose While On Antibiotics

So when I started my antibiotic treatment my doctor's office gave me a little informative paper describing how to take probiotics. It basically said to take two doses daily of acidophilius, at least two hours away from the antibiotic dose (4 pills all at once each dose) So basically something like this:

Antibiotic, >2 hours, Probiotic, Antibiotic again 12 hours after previous antibiotic dose, >2 hours, Probiotic.

Later I spoke to him on the phone and he specifically said to just take one probiotic dose daily, and he also told me to up the dosage to 6 pills. Maybe the paper his office workers are giving out isn't updated? Either way, I'm looking to find out how often (daily) and what dose everyone typically follows. "4 pills all at once" means nothing to me when probiotic capsule A could have 500 million organisms and capsule B (different brand) could have 4 billion organisms. So far I've been taking 6 capsules of acidophilius for a total of 6 billion organisms, and one 5 billion organism capsule of JARRO-DOPHILIS EPS which is 8 strains: L. rhamnosus, Pediococcus acidilactici, B. longum, B. breve, L. helveticus, L. casei, L. plantarum, and Lactococcus lactis ssp. lactis.

Any input would be greatly appreciated, although I would specifically like to hear from those who have stomach issues taking antibiotics (diarrhea, constipation, excess mucus in stool, loose stool, going multiple times per day, etc.)

Thanks for the response. I'm mainly thrown off as to the proper dosage. I realize that this varies depending on the individual. I'm taking 11 billion per day, which I thought was a lot, however I was told by another lyme patient that they are taking 80 billion organisms per day! I'm not opposed to taking more, I would like to experiment, I'm just wondering if this has already been figured out typically to save me some time.

I take 3 - 12 billion capsules twice per day, two hours after each abx dose.  That makes 72 billion per day.
