Thnak you so much, Bee123 and Sheryl! I'm just now seeing your posts. They give me hope.
Now that I'm past the initial shock, fear, avid researching, and obsessive forum-reading, I've pretty much accepted that I have this thing, and I'm not inclined to let it ruin my day. My symptoms are very mild and, like everyone, I hope they stay that way. If things start going downhill, I know that I'll travel to Vanderbilt for surgery, and then take things from there.
