the blood patches don't work?

I'm quite interested in someone explaining the use of caffene to help stop the headaches. (i'm completely new to the game)

I'm due for another LP next week and a bit worried about the headaches as the first and last one i went in for was 5 unsuccessful LP's which must have leaked as I was flat on my back for 6 - 7 days and still not completely better yet but enough to walk around and finally take care of myself!

I hope you find a solution that works for you mark!
