Yes - I was on Antibiotics from 2 weeks old and pretty much every year since then until I was a teen. I had mono in 4th grade, went on a high carb / low fat diet all throughout high school and then birth control / fast food /caffeine in college. After having two kids my system is taxed out entirely. every time I've taken Antibiotics , the infection will die out but I'll end up with less and less energy.
