Nonsensical

I would stress this point HARD.

Stopping alcohol intake following a protracted period of persistent use can cause temporary anhedonia. Habitually spiking one's dopamine levels with booze causes the brain to respond by increasing the hedonic setpoint - the dopamine threshold for feeling pleasure.

Anyone experience the phenomenon of needing more and more alcohol to get the desired effect? That's your brain raising your hedonic setpoint. (Turns out its bad for survival if you sit around buzzed all day and forget to hunt or gather. Your brain is fighting back.)

So you keep drinking more and more. Before you know it the normal things don't bring much pleasure. The only thing that does the trick is booze - more and more booze - pushing your hedonic setpoint higher and higher...

Then one fine day you realize your life is turning to crap and you stop drinking. But your hedonic setpoint is still elevated - and whammo, you've got anhedonia. You don't feel pleasure. The world is blah. Everything is blah. You could be at Disneyland and wonder why everyone is having fun except you.

Give it time. It takes months, but your hedonic setpoint will come back down from its artificially raised state and simple things will once again bring you pleasure. The anhedonia lasts a while, but it is TEMPORARY. If it takes more than 6 months, see a doctor. You might have more going on.
