In my uneducated strictly PERSONAL opinion,,,,,

I believe most Dr's would agree that a weaning off process will take 10-14 days at an absolute minimum.

Based on actual experience, talk to your Dr and explain that you would like to have an emergency stash and most will write you a prescription for a 10 day supply with no refill authorization, OR when you are due for a new prescription, they may write you a normal prescription times double dose so you can take the extra and make yourself an emergency stash. It greatly depends on how well your Dr knows and trusts you to do as you say you are going to do. It doesn't hurt to ask and I have yet to hear of a Dr laughing at a patient's concerns in such a matter.

That's how I got my 10 day supply of (broad spectrum) antibiotics that I carry with me when I deploy to work. I've used them once and let my Dr know when I used them and I scheduled an appointment as soon as I got back home. It is always prudent to have a follow-up visit after taking/needing those antibiotics. I also called his office prior to taking them and described my symptoms and asked if he thought it would be a good idea to take the antibiotics until I could get home.

Perhaps our Dr's down here are more understanding of the medication possibilities since Hurricanes Katrina and Rita brought the need for emergency meds to be on hand, more to the forefront.
