There have been cases of people getting worse while lying down but caffeine pretty much works for everyone although sometimes nothing works. When i say caffeine i mean like 3 shots of expresso all at once. For me it doesn't kick in right away pressure will be reduced after a couple hours. Batman, have you ever tried a drug called amytriptiline? Im not sure how expensive it would be without insurance but it is usually very succesful with these types of pressure headaches. Im on it and while it doesn't help my head it allows me to keep my mind of the pain and not get frustrated and anxious. I think it would help you.
I'll look into it, thanks.
Actually I find if I have really concentrated caffeine drinks--like the 3 shots of espresso--my head pressure gets so much worse, the worsening effect can last for 1-2 days before going "back to normal." I get around this by just drinking more of the regular strength stuff, while avoiding smaller amounts with more caffeine.
I haven't been able to have caffeine pills or anything "concentrated" like that for years, because of this, and other strange symptoms brought on by that.
Curious, does alcohol make your pressure worse or better? It used to make mine less noticeable for a few hours--granted I drank enough--possibly because of the painkilling action of ethanol.
