@robert-stuttaford: thanks for saying that my previous caffeine intake was quite high. It helps me to push through. Sometimes I think it's normal, because I've got colleagues who drink even more coffee all day long

of course it's an individual thing, how sensitive you are

my pleasure 🙂

coffee consumption is among the highest in The Netherlands. I even drank it as a kid

one might expect the reverse, but last three nights my sleep was really bad

it will pass! hang in there

Time to start watching Cloud Atlas, and then later Metropolis!
