MsHopalong - I am in the exact same boat. My cramps are debilitating and absolutely interfere with my life. I find myself planning everything around when I am going to have my period and be incapacitated. What really stinks is when you have obligations you can't get out of...just adding more anxiety on top of all the stress and pain you already have to deal with...
I'm 38 and have experienced this my whole life. I have told every single doctor I've ever had and have been dismissed as "well, all women experience this, it's just something you have to deal with". I do not have a low pain tolerance...I have a lot of pain! I find myself not even wanting to bring it up (again and again and again) and come across as an over-exaggerating drug seeker.
I do the best that I can by managing these monthly episodes with Aleve, Vicodin (if available - not exactly an easy thing to get from your dr these days), a heating pad, and rest (also not so easy to come by with children and other obligations).
I do not want to go on any type of hormone therapy because I'd like to have another child...
Haven't heard of "Cope" before, but will definitely check it out...
Good luck ladies!
P.S. People used to tell me that my cramps would get better after childbirth...not true! In fact, I feel as though my cramps during childbirth were less severe than the ones I have to endure every month.
