Awful, awful cramps. Advice is needed!

So the oh so lovely AF came to visit today and she is wreaking havoc on my insides. I have NEVER had cramps this bad. It gets to the point that I want to cry and throw up because the cramps are constant, and awful. I won't wish it upon my worst enemy.

So, ladies, how do you cope with cramps like this? I've been using a heating pad and taking pain reliever but they are ruthless, and I cannot sleep because of the pain.

Oh, and what helps your back pain? Any advice is greatly appreciated, ladies!
