e-head, I can't imagine having to live with these headaches for a year or two or even longer! Mine usually start right after I get up in the morning and get better by afternoon - just not today. I don't remember having any tingling, but I do get a weird feeling from caffeine, like popcorn popping or a pingpong ball hitting the inside of my head. I have cut down to half a cup of coffee in the morning and some tea in the afternoon.

I really hope that your symtoms will go away fast this time, good luck.
