Thanks a lot guys, I did enjoy having a good sleep for the first time in a week, but unfortunately, as soon as I had posted here, I fell asleep again. When I woke up, I was still feeling groggy, but figured some fresh air, and a couple of cups of Charlie's coffee would wake me up. I went into town, and bought a few groceries, but then fell asleep again as soon as I got home. While out, I'd also noticed that my nose was a bit stuffy, and that my sense of taste was slightly diminished. A couple of friends had mentioned there were some strange viruses going around, and so I had a look online. Turns out that there is currently a huge spike in a new Covid variant here, and I have most of the symptoms - difficulty sleeping, feeling heavily fatigued, brain-fog, a stuffy nose, a change in taste, a cough (which I have anyway)! I also had a sore throat for a few days about a week ago. The fatigue, which is just like you'd expect with a case of flu is annoying, and the difficulty I've had sleeping, but the other symptoms are very mild, and if I do have a virus, I hope I'm soon back to normal!
