The good news is that there are great reusable alternatives. They're cheaper in the long run, safer and way better for the environment. As Emily from Food Origins once commented:
Re: pads, tampons, rags...my favorite answer is "None of the above." Try the Diva cup or the Keeper. This is a silicone or latex cup - like a big thimble - that you wear internally and empty and rinse periodically. WAY cleaner than any of the usual Western methods and no waste! I know half a dozen women who have tried it, and not a one of them will go back to any other sanitary product.
