Can she go to mail order meds? We take a bunch of pills daily (seems like more every year), we get a 90 day supply by mail. The refill notice comes early enough that I can usually get a refill while I have a week or more on hand. I have been doing that long enough that I now have 'bout an extra 90 day supply on hand, so if something happens as refill time approaches, I am still good to go. Or, you might sit down with the dr, explain your concerns, and get some extras thru him/her.
Last thought, could you go to Mexico and get some there? I know a lot of people, without med insurance, who run across the border to get their meds. Most are not even checked when they cross back...
