I still get waves of hyperactivity and exhaustion. I like to imagine that it’s my brain chemistry readjusting back to normal.
From what I’ve read about alcohol and brain chemistry, alcohol acts like a handbrake on your brain’s performance. Your brain is regularly being slowed down by a depressant (alcohol) so it becomes used to revving really hard to drive at a decent speed. So it’s like you’re driving with a handbrake half on and the motor screaming – then you suddenly release the handbrake and the car lurches forward. It takes time for my brain to adjust to ‘new normal’.
It’s that depressant effect which can lead to seizures, major brain disturbances and death with chronic alcohol dependency. Alcohol is such an common everyday drug – but sudden withdrawal from it can be surprisingly dangerous.
OR it could also be the copious amounts of coffee that I’m used to drinking to get me through sleep-deprived, hang-over days… combined with our gigantic work Christmas lunch and piles of sugary desserts. Hmmm
