I simply took a probiotic after being on antibiotics for a couple months and it had a side effect of curing a lot of digestive problems I used to have.  So there&#x27;s that, too.  Incidentally, my doctor was the one who advised this.<p>EDIT:  The probiotic in my case was capsules of 15B cells of Lactobasillus GG.  Marketing copy on the box suggests this is the &quot;most clinically studied probiotic strain&quot; but I&#x27;m not able to verify that.
