I bought my first box of Insteads the other day (love them! If they work out in the long run, I may think about a Diva Cup or something) and posted about my experience in tmi_chix, where a couple girls responded saying that they don't dispose of Insteads after the recommended 12 hours but clean them (at least once a day) so that they only need to use one per period.
Now, I'm all for saving money and reducing waste but I'm probably not going to try this myself. I'm just wondering if you guys have any related information or experiences to share. Thanks
