"Saving relationships, one month at a time!" That's the motto of www.PMSBuddy.com, which got its start during a LoDo happy-hour bar discussion. Unlike so many booze-inspired ideas, Jordan Eisenberg turned this one into reality, creating a free service currently tracking the schedules of 37,000 women, and it's even available as an iPhone app. As the site notes, "PMS — premenstrual syndrome — can be a difficult time of the month for many women and those close to them. Since discussing PMS is not exactly welcomed dinner table conversation, and may lead to dinner plates being hurled across the room, we want to take the unexpectedness out of this recurring occurrence so that those affected by PMS can be prepared and aware."
