I was going to offer the same suggestion that Candc offered......yogurt is the best thing to eat after taking antibiotics.....also, there are OTC tablets that are probiotics that you can also take.....I got some at CVS pharmacy......they also help in getting any constipation from happening also....sort of get the body working again the way it's supposed to & that is better than taking laxitives or stool softeners because it helps your body function naturally again. Yes, antibiotics really can mess up the system. That's why I don't take them unless I don't have a choice...but usually I try to allow my own body to fight off infections....only if it's not working do I resort to antibiotics.

When I was a kid, I was constantly sick & the antibiotics then caused my teeth to form without enamel so I had all my teeth breaking off & finally had oral surgery to remove all my teeth just this year.....totally a miserable experience.
