Fellow girls with endometriosis- what do you do to manage your cramps?

First day of period's daily routine begins with calling off work, crawling to the nearest water bottle, plugging in a heating pad, and laying in the fetal position crying until the cramps have passed.

Tips I've learned: mashed potatoes are your friend, heat pads that you can stick to your stomach and walk around with, screaming into a pillow so noone hears your suffering

Does anyone have any tips dealing with your cramps or how to make them better?
