It's not so much the cramps as the pre-cramp cramps, when it feels like you have a stomachache and nasuea and someone yanking on your abdomenal muscles.
Seriously. No fun.
In happier news, I have finished my crackfic (yay!) and it is returned from le beta (yay!) so this afternoon, once I have a chance to look it over again, I will be posting! On john_teyla first, as promised, and then here, and at some point at psych_30 since I'm using one of the prompts.
