I suffered with Endometriosis for about 11 years. I would have horrible cramps that would cause me to throw up from the pain. I’ve been taking Endovan for almost a year now, and I no longer have to take any pain meds at all during my period. I did stop taking it a few months ago for a couple months to see what would happen. The endo pain did return, but I got back on it, and I’m feeling great again.
