Portland to Portland - Driving around the U.S.

I don't get migraines often, maybe once a year I see auras and I take 4 ibuprofen and I get a headache but it's a dull roar. Yesterday afternoon, when I saw some auras on the way from the wine tasting, I thought I'd do the same. Well, I had the worst migraine, by far, that I've ever had. I had a brain squeezing, can't keep my head up, nausea inducing headache that lasted for 14 hours! That has never happened before. Who knows what triggered it...the total of 2 glasses of wine I had over 5 hours, being so tired after the ferry trip lack of sleep, the heat...who knows. I only knew that I had today to check out Seattle and I still felt nauseous with a slight headache this morning. I was planning on hitting Pike Market by 7:00 a.m. and knew it wasn't going to happen. So, made myself some tea, took a shower and got some crackers from the hotel pantry. I checked out the public transportation schedule, told myself to suck it up and headed into Seattle around 8:30 a
