Why do i feel bad after i get drunk? is this normal?

I think that you've got a very bright future ahead of you, you just need to come to terms with yourself and who you really are. To be honest, I think that the whole party lifestyle is overrated and rather pointless. It's understandable if you want to go and have some fun and hang out with friends, but nowadays people just drink and party all the time because it's the "cool" thing to do, whether they enjoy it or not. I think most people actually don't. You feel bad after getting drunk because subconsciously you realize that you could be ruining your intelligence and throwing away your future. I'm not saying it's all that serious, just that you need to be careful with the whole drinking and partying and smoking weed thing, because although it isn't really affecting you now, you can get more and more comfortable with it and throw everything away just to live in the present. Also think, although you may be missing out on some parties now, how much fun will you be having after you've graduated college/university with a degree in engineering and are making a bunch of money? Is it not worth it later on? Besides, how much are you REALLY missing by not going to a few parties to study? It's called responsibility and you'll have to come to terms with it eventually anyways. Just have fun now, but keep your eyes on the future as well. If you feel like you're making a bad decision, don't do it. That's your conscious telling you what's right and what's wrong.
