A couple of big bottles of aspirin will come in handy too. Could save your life in a heart attack, limit a stroke and is a great pain killer.
A lot of the need for antihypertensives and diabetes oral meds will vanish if the SHTF ever happens, because people will lose weight and get a LOT more exercise.....
The aspirin is a great idea, but ALWAYS buy the coated. The shelf life is over 10x the uncoated.
I’d suggest Tylenol as well as aspirin. There will be times you’ll want a painkiller that is NOT a blood-thinner.
