Brian thank you for posting this.
I was having the exact same experience, and nobody could validate it for me. I gave up drinking completely, sober date in signature.
It got so bad I could have one or two drinks and be tossing and turning, crying, anxiety-ridden, useless for five days. When just a few years ago I could go on 15 drink benders, then get up for work the next day.
I don't understand the science behind it, but I KNOW it was not "all in my mind" or psychosomatic.
I wish I had not been in denial about it for so long and given up drinking a lot sooner, just faced the fact that something in my body had changed permanently and any alcohol at all was ruining me.
Just know that it is a real thing.
