I'm sorry you got "caught" like that. Whenever I travel, I take one week more of my meds and supplies then I need. I have four of those weekly pill boxes and when I get my prescriptions I fill all four of them and then I don't have to fool around with all of the pill bottles for a month This makes it easy for when I travel, too. I just grab what I need plus one more week.
I'm glad you made it, though. It's horrible to be in pain and not have what you need.
