It's so nice to find out I'm not alone with this crazy thing. Every doctor I've mentioned it to just kind of smiles and says they have never heard of such a thing. I also get hypnic headaches during the night every night and was wondering if there was some connection but my migraine specialist has never heard of it. I also get up a lot during the night to urinate but thought it was from my old age but could there be some connection to that also?
