I was in the scary chair for over an hour with my mouth open. Some people say I seldom shut my mouth but today I'd have to agree. It surely felt like a lot of drilling, filling, and smoothing. Thankfully, I felt nothing except the first two shots into my lower jaw.
Before driving home, I walked a bit uptown. I checked out the London Drugs computer section but didn't see anything exciting there. I'm checking out the options for a replacement travel computer. I want absolutely minimum weight with a 14" screen. There's no rush as the present Windows laptop has been around the world a few times but is in working order.
