I seem to have encountered a Catch 22 when considering medical supplies. If I presently do not require antibiotics, then I have no way to acquire them for a time when I might need them where getting to a doctor may not be possible. And doctors do not want to randomly prescribe antibiotics for a person to store, make their own assessment of what is needed, how much, and take the antibiotic. So with that said, I often see posts that talk about getting medicine manuals and using various pet supplies (e.g., fish antibiotics) as a means to have an antibiotic on hand. Is there a book or somewhere to get good reference material on a) is this even a reasonable / responsible option, b) if not, what are better options, c) if so, what to buy, where to buy it, and how & when to use it?
