Every now and then we get the slew of questions about can I use cups doing this, that, or the other activity, and the answer is usually yes, you can. However, I didn't remember anyone asking about riding roller coasters, and a quick search through the tags and memories confirmed that we'd discussed it briefly, but never really said yes or no definitely, so I thought a quick post might be in order.
I went to my favorite theme park yesterday, on a heavy day of my period, rode all the coasters, and my Divacup did just fine. Nary a leak. So, that in mind: roller coasters are a-ok with a cup in, if that's your cup of tea. :)
Just wanted to share that in case this question comes up in the future!
