Don't panic, I'm okay. I either had a severe migraine or an allergic reaction. Hopefully I'll find out more when I see my doctor this morning. I had all my usual migraine symptoms - numbness in face and leg - but my tongue also swelled up and I couldn't speak. Apparently, I'm a medical mystery. I always knew I was a bit odd but this just proves it (I recently had an MRI, so I know it's not anything more sinister).
I've been told to take it easy, which is a bit difficult when you're in the middle of Nanowrimo. But Friday night did scare me, so I'm taking note of the advice. If I take longer than usual to reply to comments or emails, please bear with me.
I hope everyone's Nanowrimos or WIPs are going well. Keep writing!
