Question From a Fearful Non-Drinker Who is Drinking-Curious

So, I come from a long family history of alcoholics, in a very alcoholic-friendly village. I always assumed I’d start drinking at some point, but never did. Now I’m 30 and have never had a drink. The idea of being intoxicated is one of my biggest fears, and being around drunk people wigged me out for a long time, too. I’ve calmed down a lot and have found a lovely community of people who drink responsibly.

I would like to face my fear. I really like the idea of being able to have one beer at a party, or just being in a position of not considering myself always a non-drinker.

I want to try drinking a beer or cider alone in my home, just to know what it feels like. I know that one 5% can is not considered a lot of alcohol, and wouldn’t produce much of a buzz for regular drinkers, but since I’m a ‘virgin’ here, should I assume my tolerance is low or should I consider it an uknown? Also, how does the intensity of a hangover correlate to what you drink?

If I were to drink one can of beer or cider and get a buzz from having a low tolerance, would I have a hangover the next day?
