Vertigo. I was carrying a load of heavy bags into the bus station lastnight and vertigo hit me like a truck sending me staggering into one of the barriers which I had to cling onto until davem rescued me and the customer service people got us a taxi. Then I slept 12 hours solid and have been unable to raise my head from a prone position for much longer than about 20 minutes all day long, and have spent all day lying on the settee watching rubbish on telly. On top of that I have constant nausea, a headache and a stiff neck. Probably all from carrying two litres of Ribena in my rucksack until my shoulder blades felt like they were going to come apart.
