Thank you all for your positive energy, kind thoughts and prayers...It definitely helped (and has made my poor tired wife smile a little at long last after this week
I'm back home now after a round of being poked and prodded- Ruled out (in order on my notes) meningitis, an intercranial bleed, hydrocephalus, lesions, infarction, an aneurysm or any stroke. .....Current working theory is a bad cluster headache or migraine due to the stress I've been under and lack of rest- as diagnosis go that's a 'take the money and run' and thus I did.
....I'm feeling back up to 99% now- just that 'jet-lagged' feeling you get from trying to sleep in a hospital ward with constant foot-traffic and alarms going off left and right all night.
I've got to go back for an angiogram later in the week to rule out any issues that might have been hidden but that's a backstop against anything caused by them delving around in my wetware in '08. ...Apart from that: quiet rest at home and destress.
Warhammer 40000 is- basically- Lord Of The Rings on a cocktail of every drug known to man and genuine lunar dust, stuck in a blender with Alien, Mechwarrior, Dune, Starship Troopers, Fahrenheit 451 and Star Wars, bathed in blood, turned up to eleventy billion, set on fire, and catapulted off into space screaming "WAAAGH!" and waving a chainsaw sword- without the happy ending.
