I agree that for anyone that is dependent upon certain medications it is prudent to build an emergency stockpile of the pills or devices you can't do without. Many cruisers (sailors going out for extended trips) have similar needs and in addition need emergency medical kits for the boat. There are doctors and online drug stores that cater to these folks. Might be worth researching who they use. I would exercise caution with any supplier of meds that you are not SURE is getting you the right stuff. Snake oil salesmen they were and are (meaning the entire pharmaceutical industry but especially sketchy on-line places).

Better, from a long term resiliency point of view, is to make a concerted effort to wean yourself off all those drugs. Be honest, the BP meds you are taking probably wouldn't be needed if you were 25 lbs lighter, right? And how many of those other ailments we all deal with, especially as we get older, could be managed nutritionally or with locally available herbs?

I manage my borderline high blood pressure AND occasional heart palpitations with hawthorn berry extract. A friend uses it for his atrial fibrillation. I gather the berries in the autumn and make a year's worth for the cost of some vodka and my time. Obviously, you should proceed with caution when using or changing any medication, whether made by yourself or by Big Pharma. But I have seen many times that the best treatment for many people is to stop taking all their meds and see what is actually needed, most of which are being used to treat the side effects of the previous drug, which was treating the side effect of the previous drug, etc.! If your doctor is one of the rare breed that is actually interested in your long term health, talk with her about your desire to improve your health and reduce or eliminate if possible, all purchased medications. You might be pleasantly surprised at their willingness to help!
