I asked why you found it enjoyable and you didn't respond, so it's hard to explain the author's viewpoint when you haven't explained why you drink.
To give generalised responses to the three main reasons that people give:
- Do you enjoy the taste?
- Alcohol is ultimately a foul-tasting poison. No one ever liked their first taste of beer. We start with highly-flavoured drinks like alcopops and after a while our body says "well you must have a damn good reason for imbibing this poison, so I'll stop warning you as much".
- Do you think it helps you relax?
- Alcohol dulls your senses. I'd consider relaxing to be a sensation, and so in this respect it can't help you relax. On a deeper level, generally to relax you need to fix the thing that would stop you from relaxing - you have a headache and you take aspirin. Alcohol is not the solution to any stressor.
- Do you think it's necessary to enjoy social situations?
- Think about children at a party. They turn up very shy and within 30 mins are bouncing off the walls. No alcohol needed. Adults are the same. And we all have multiple memories of social events that have been ruined by alcohol.
