Sleepy fuzzy spiky

Slept.
Woke up with nasty headache.
Went back to bed.
Slept.
Woke up, feeling like my eyes were being stabbed and my neck almost completely immobile. Felt queasy. Vapour trails all around and a lack of balance.
Migraine alert.
Tablets.
Sleep.
Lots of sleep.
Woke at 7.30 this evening.
More tablets.
Managed to keep it at bay I think. Managed to keep food down.
Feels like a hangover which is grossly unfair as I didn't have a drink last night after all.
Bed again soon.

(Corin's glasses, with light shone through them. My glasses create a different light cone. Difference in cone size and shape to do with the strength of lens in each eye? Probably)
