What is it meant that alcohol affects everyone differently it doesnt make everyone feel happy ? maybe some feel just relaxation is that what is implied here ?

If you ever ask a patient that drinks too much alcohol, they almost always under-report the amount of alcohol they drink, I saw a young man months ago, who had liver toxicity from drinking too much alcohol and as I warned him he was convinced I spoke to his mother about his problem. There is that defensive block about alcohol - like a destructive secretive "friend" that they don't want to give up

Alcohol can have calming effect on some people , whereas can be stimuant for others. Thus alcohol can make some people sleepy, can also lessen pain & can depress you. On the other hand alcohol can give self confidence, can reduce oe even remove inhibitions or unfortunately become aggressive both emotionally or physically. It can also lead to addication. Hence alcohol affects everyone differently.
