I googled around for this new “Cum Tums” product and found a bunch of things that made me kinda uncomfortable, so I'm not really sure what Tums is pitching with this new Muni advertising campaign.  I think it has something to do with heartburn, denigrating gender stereotypes, and calcium deficiency.  Also, my googling leads me to recommend that you don't try to fit one of these chalky discs in your urethra.

Have a lovely commute home!
