My experience with alcohol
when i started going out i wasn't drinking at all. i went a year of nights full sober, sometimes on weed. later i found wings and they were always drinking and i started drinking.
Alcohol makes you stop analyzing and worrying how you are perceived by people. it makes you present to the moment.
When going solo or you're a begginer and have really hard time approaching or you are very shy alcohol tremendously helps :) (i think it's good to use alcohol just to start the wheel spinning and get your first references because when i went solo for a year there were lot of nights where i couldnt warm up and ended not approaching a single set or not being in state)
Most people drink or are on drugs or very unstifled in the club (especially at second part of night)
so if you are 100 % sober it's harder to connect with people.
Lowers your time of getting in state and not always but often bringing your 'A' game (as explained erlier)
When i go sober i tend to get aware of how am i feeling and could consciously unstifle myself in subtle ways (asking a stranger the time,how full is the club or some question, slowly dancing,doing the golden phone call (caling a buddie and chattin and joking with him on the phone) planing your day and daily activites that are productive or that it will get you focused and in state (having a cofee with friend, going in social place during the day,meditating,eating clean foods...)
when i know i'll drink and drink alcohol does a lot for me in terms of needing to unstifle and be in state so i don't pay attention or neglect most of these things.
Even thought you are present you are also kind of numb and your senses are not working fully. so your not coming across as fresh and calibrated.
When the alcohol of effect subsides i feel tired and numb,not focused and bored. this ussualy happens in the second part of the night (where it most counts if you're 'ON')
it's unhealthy and i feel really bad the other day sometimes. (every artificial high has a down)
If i continue to drink couple nights in a row i get very tired and lifeless at the end of the week.(although i have momentum from nights before and i am socially still a bit ON)
-Guys with driving licence and a car are fucked unless they get a cab or live very close to the clubs.
Spending money (Esspecially if you plan on drinking in more expensive nightclubs.) Conclusion
if you're new and have very hard time opening and being relaxed or have lost all macro momentum use some alcohol. but make this exception not the rule because you may get addicted to drinking before going out. as long as you plan your week and are aware of the bad sides of alcohol use it carefully. it's not that bad and is positive in MODERATION.
the ideal is being fully sober and being in state and unstifled. eventually as you progress or go out often you have to lower or stop the amount of alcohol you drink.
