Hi Hoping,
What you are saying is something I have heard over and over again for years from others. I really don't understand all the scientific reasons for this, but's it a common complaint. People go on antibiotics, then go off of them only to feel worse and start feeling better once they go back on them. It's like a vicious cycle.
I think we have become antibiotic-resistant, just my humble opinion for many reasons. In any case, it's no secret that I became better using alternative medicine and heavy detoxing after reading Dr. Jernigan's book and using his "healing at home" protocol.
Anyway, Dr. J. wrote this:
"Some people only feel good if they are taking the antibiotics. This is possibly due to the fact that some antibiotics work by impeding the growth of bacteria without actually killing them. Again we see an unacceptable solution, since this leads to years of dependency upon antibiotics. This is justified by some, due to the relief the treatment provides, even though it is but again simply a drug-induced illusion of health."
That statement comes from this article:

Hope you feel better,
