i have endometriosis, and a lot of girls with endo skip periods so they aren't in so much pain all the time. i tried it once, and will never do it again, i was in so much pain i thought i was gonna die! my dr. said that some women don't do so well skipping periods and told me it pry wasn't a good idea to try it again, which kinda sucked...i don't know if this helps or not, but i feel where you're coming from!
