These are good questions that don't necessarily have concrete answers.
As for sex, there is no mandate outside the monastic community except that you should "avoid sexual misconduct". Sexual misconduct is described as:
1. Sex with someone against their will.
2. Sex with someone who is married (unless they're married to you).
3. Sex with someone who is engaged (or otherwise "off the market").
4. Sex with children.
The Buddha had nothing against sex. The problem is lust, or the desire for sex (you'll notice that in Buddhism everything comes back to the problem of desire).
As far as intoxicants go (this includes alcohol), it's kind of a gray area. If you have taken refuge (which I'm guessing you haven't, course I haven't either) you have to swear off anything that hampers your ability to see the world exactly as it is (i.e. something that gets you high or drunk).
HOWEVER
Please please please don't think of these things as something that you'll be punished for, like a "sin". There is no cosmic lawgiver to judge and punish you for your actions. Just know that if you drink too much, you're going to lose any wisdom you would have sober. And that may (or may not, you may be a happy drunk) have negative consequences on your life.
