I just wanted to ask a question about your CSF production. Are you saying that your doc is treating your headaches by reducing your csf volume? And if so, do you to know that caffeine is a major csf stimulant. I had to have a spinal tap to rule out MS and the neurologist "prescribed" 2 cups of very strong coffee 1 hr pre-procedure. She said it would bump up my volume therefore reducing the post-procedure headache. It did help afterward, I had more back pain than headache.
