What is the best method to neutralize the smell of poop in a shared, unisex bathroom at the office?

I work in a small office, and share a unisex bathroom with the rest of my co-workers. I also suffer from IBS, which means I poop frequently during the work day (usually 2–3 times during the workday, pardon the TMI.). I am wondering what the best thing to do, to neutralize the odor, after I poop, but before I leave the restroom? Please help me.
