I second the suggestion to talk to your doctor. Worst they could do is say no. Just don't be stupid about what you ask for (antibiotics is a lot different than a narcotic pain killers for example) and be straight up with them why you want them (remember, Docs have a lot of experience with people seeking controlled substances). Besides, preparedness isn't something we should be ashamed of.

My Doc actually seemed to perk up at my disclosure about disaster preparedness.

I recall a thread here a long time back where it was asserted that there are only a couple of meds out that when you really need, you really need (individual Rx meds aside) -- EPI pens and antibiotics.

This of course assumes you have an ongoing and good relationship with your doctor. If you don't have one, I'd suggest getting one. Think of it is another exercise in preparedness. :-)
