Hi, how are you doing? Good evening or afternoon depending on where you are. I have been away for a while and I'm probably going to be away for the next while. Probably a few more days up to a week. I've just been in the middle of post-exertional malaise and I don't even have the strength to explain what that is, but the abbreviation is PEM. If you look it up you'll understand why I haven't been around much, but I will be back soon.
