Alcohol sedates or slows-down the brain/mind to produce calmness or relaxation, same as the action of more natural GABA being produced at night in normal people to prepare their brain/mind and body for sleep.
Afaik, drunkenness from excessive alcohol consumption equates to the brain and body having been completely shutdown like in a coma, ie not the normal deep sleep of about 4 hours (and then REM/Dreamy sleep for about 2 hours). Hence, drunk people at pubs/bars also cannot walk properly before they pass out.
I was referring to non-drunkenness, ie drinking alcohol just enough (eg 2 cans of 5%-beer or 1 glass of 14%-wine) to calm the brain/mind for sleep, which then can disrupt REM/Dreamy sleep later, ie after deep sleep.
Yes, withdrawal symptoms are often very weird, eg paranoia, hallucination, delusion, etc, even during sleep = an over-active brain/mind.

Yup, I am no doctor but I can associate that my brain just like go into overdrive after I remove alcohol because its a suppressant of brain activity.
In contrast energy drink or coffee its a stimulant, also affects brain activity and as brain tries to go back to normal levels, it starts to cause withdrawal.
I did not purposely quit coffee or energy drink but one time I drink more than one Redbull, my hands was shaking, so I quit.
Only last hurdle is anything alcohol.

If anyone want to drink to their death, is their choice but I've been to the far end and its not a good feeling.
