Is my tolerance to Vicodin any reflection of tolerance to alcohol?!

So I am 18 and I don't drink but I'm worried that one day if I do try alcohol (once I'm 21) that I will become addicted. I used to be "addicted" to candy and pop. I would drink like 6 glasses when we would go out to eat. So about 3 monthes ago I stopped pop and candy complete and have had like one can of pop since December.

So down to business, I got my wisdom teeth removed and I was a little worried I may become addicted to vicodin and it's effects. However, I have been taking 2 every 6 hours and barely notice any "high" effects. I am a little dizzy but not that much at all. Some of my friends are recreational users of vicodin and says it gets that all chatty and happy and stuff, but I haven't noticed any effects like that. Is there any relation between this and alcohol use since their effects are kind of similar? Thanks.
