I don't drink - sobriety is no worse than drinking alcohol.
You are your brain. Literally. That is, if you are like me and have a rather materialist perspective. Every single neurological study has given more and more proof to the idea that you don't "have" a brain, you ARE your brain. That bundle of nerves, glial cells, axons, dendrites and synapses? THAT. IS. YOU.
Now, contrary to popular opinion, Alcohol, consumed in moderation does not really kill brain-cells or do any long-lasting damage to the brain. It does, however, affect your brain chemistry and can affect it quite a lot. That affects your personality as well.
I won't do that to myself. I am one of those people who firmly believe that rationalism and the human intellect are the only things worthwhile on this entire planet and indeed, in the observable universe. I will remain myself, at all times. I will not blunt my intellect, I value it too much. This is not to say that I have a genius level intellect - I do not. I am not a genius. We all have a valuable intellect that should be safeguarded. We all have an intellect that we depend upon. I just seem to value mine more than a lot of other people.
Plus Alcohol is:
1) Addictive. You know it is. A lot of people have alcohol problems but they never admit it.
2) Increases your chances of cancer: This has been proven in various medical studies in the Lancet and the BMJ.
3) Damages your liver
4) Expensive
5) And can have serious consequences. It's all fun and games until you've wrapped your car around a tree! I'm a med student - I've actually BEEN to car crash sites (mostly to learn procedure, but I've been there). It's not very bloody pleasant, to see someone shrieking in pain due to a crushed pelvis, flail chest segment, broken arms, and blood pouring from their mouth.
Now, of course, if you can moderate your drinking, you're fine. You'll avoid all of the above. Being a moderate drinker means you probably won't drink and drive, you'll probably avoid any long-term damage to your liver, you'll avoid addiction, you'll avoid the expense that comes with addiction and you'll only marginally raise your chances of getting cancer later in life (equivalent to eating a beef-burger every now and then, it's mostly harmless). So if you are a moderate drinker, good on you. You'll have a fun time and you'll stay safe.
But how many of you are? Time and time and time again I've seen people vehemently deny that they have a drinking problem.... until it's too late.
Consider this possibility: If you are the type who adamantly insists that "I DO NOT HAVE A DRINKING PROBLEM!" If the mere accusation of addiction is enough to send you into a rage, if you always console yourself with the canned line "I can stop at anytime!" then maybe you do have a drinking problem!
While there is nothing wrong with moderate drinking, there is nothing wrong with teetotalism. Unless you are the type who thinks it's impossible to have a meaningful, entertaining time with others without alcohol, which in that case.... that's a damn shame.
