I think Buddhists have the best answer: Strive to tread the middle path. Or as one of the Greek philosophers said, "All things in moderation." I think the Bible says that somewhere too.
Going too far with anything can be hazardous. For example: Too much alcohol causes hangovers, alcoholism, bad behavior, dangerous driving, etc. But if someone is the total opposite--no drinking alcohol in addition to being judgemental about others who use it, wanting to ban it, taking it away from others, etc....that's an uptight, prudish a$$ whom few people enjoy being around. (And the prude is probably chronically unhappy too.)
So indulge sometimes; just don't make it a way of life. That's called hedonism--the pursuit of pleasure at the expense of all other things.
