I have the same exact problem - for 3 years now. The pain is excruciating at times for me. I've been vegan for a long time, and every doctor tells me that no vegan gets this problem! Ugh. I've been drinking Dandy Blend for 6 months now. I used to have an attack after eating ANY fat, or during natural hormone shifts (ovulating, etc.). And they were bad attacks. I called 911 more than once, thinking I was dying. Since drinking the Dandy Blend, I've had a few minor attacks, but nothing like they used to be. I definitely don't think it's a cure, but can help until something better comes along.
