Coffee should help

But sadly that vessel was already empty and I was sitting in the middle of a row so I couldn't get more without disrupting everyone around me.

I stuck it out for a while before deciding "to he'll with it" and initiating the disruption. I did stand at the back for a while afterwards, which allowed me to become more than adequately caffeinated.

It got me through 'til mid afternoon. Not too long to go now - need to bail early for an MRI on my brain, to see if the problem with my right lug is vascular, rather than viral. Not sure I want to know - may be happier if the MRI just shows a large empty space, as my Mum always thought
