Tiggy aww thanks, I couldn't really - felt so crap I couldn't do anything! You know how weird things can feel at night sometimes, I was like in a fog. The annoying thing is that I don't have any paracetamols and I don't think I can get any today - they don't have it in my hotel, and I won't have time or energy to walk to a pharmacy. Strangely enough my head is absolutely fine this morning, so I just hope it was a one off and won't happen again.
Thank you so much for your support! Sometimes this forum is much better than even talking to my mum, who just goes into a panic mode and tries to scare me with all sorts of horror stories :-/
