I have used this, in my home, and when I pack, and I think it falls into the the catagory of "it's a good thing!"
Since I have started beading, to keep track of small amounts of odd beads, I bought this little acrylic storage tower. Each little jar, screws into the next one, allowing you to add or subtract when needed.
I took this one step further, and used it for my meds after a surgery yrs ago, when I had many, and I couldn't fumble with many bottles.
What I do, is, on the computer type what med it is, what it's for, and the prescription number, and tape it to the front.when its not needed anymore, unscrew it, or change the label for another med. It's compact, see though, and easy to use for this purpose. Geat to put in your carry-on as one unit.
I enclosed a link below, to show you what I mean...check it out, you may like the idea, as much as i do. I think they may sell something similiar in drug stores, but I did this before I knew.
