Oh, well nothing too sweet, or too strong. But what I'm after isn't the taste of the drink itself rather the sensation, I want to experience getting drunk.
You don't want to have just any old shit. Alcohol is a drink, a beverage. Best to have one you enjoy. Here's a few suggestions for beer. Each one of these tastes different from the other and the strength would be perfect for someone with little/no experience with alcohol. Don't guzzle, take your time. You don't know your limits and you don't want to vomit.
Leffe Blond. A fav of mine, easy to drink and a noticeable taste. People usually love it or hate it.
Ruddles Best. A very inoffensive beer, very easy to drink with subtle hints of fruit. I would describe it as a summer beer.
Hoegarrden. Probably one of those love it or hate it ones. A beer made from wheat. Having one of these and comparing it with a Leffe Blond will go a long way towards helping you figure out your taste for beers as the two styles are so different from each other.
Dublin Porter. A dark beer. If you're a fan of coffee and dark chocolate you'll find that this will be easy to grow fond of. This drink is made from dark and roasted malts and believe me, you can tell. Even served ice cold, you can taste the roast. One sip will tell you this drink was made with fire.
You might also want to experiment with cider. Can't go wrong with trying a few kopparbergs. I'd stay away from kopparberg pear, but that's because I'm not a fan of pears. The strawberry and lime and/or the mixed fruit is lovely.
You may also want to try out a blumers zesty blood orange (not as nice as the kopparberg, but I suppose that's personal preference), but I'm keeping in mind what you said about sweetness. No clue if this would be too sweet for your taste or not. But apart from that, I would encourage you to try and pick from the above. Each one is different enough from the other to be a new experience and will make it easier for you to know your own tastes.
