Felt ill right from the off, mostly coughing but also feeling nauseous, tired and headache-y. I tried a Lemsip around midday, but by 2pm I'd had it and departed for home. On the commute back I started to feel nauseous, and up chucked into my mouth while in the outside lane of the M3, so then had to swallow it again. It took every ounce of mental strength to stop more coming, and was just a horrible horrible journey. Why I didn't just pull onto the hard shoulder and puke my guts up I don't know.
I felt sufficiently crap that I went straight to bed when I got home, and felt a bit better 2-3 hours later.
I don't know what the fuck I do at this point, having seen the GP and two consultants before who can't figure out what this is. Anyway, I'll go and see the GP tomorrow.
