Yikes...I got one last night in my sleep- I hate when that happens, my head starts hurting so bad it literally wakes me up and it hurts to be touching the pillow. I thought of this thread (last night was the 1st time since then I got one) but the thought of looking at a computer screen was too painful. So here I am now...it went away after a while after I took 4 tylenol. I'm going to buy some Excedrin today though.
