My wife has similar prescription issues. My recommendation is to pull a dose or two from each prescription if she can tolerate it and stash them till you have built up a 30 day supply, then be sure and rotate that backup so they don't expire. Sometimes you can talk your doctor into writing a second prescription. They usually aren't sympathetic to the notion of stockpiling, but it doesn't hurt to ask, and if they say no, then back to plan a.
