Hi
yes it is, suddenly feel tired, lose concentration, unable to focus on computer screen, difficulty moving around due to vision and balance difficulties. workmates describe as 'me seeming to be spaced out and on another planet'. Sometimes get agitated and irritable when advised that I have a problem, I seem to want to fight through the 'barrier' instead of resting. Last time it happenend ended up with emulsion, gloss and floor paint all in one colour, brain just tripped out - employer really appreciates mis-tinting gallons of paint.
