Hey . There is a ton of good advice for you posted. If you have a primary physician it would be beneficial for you to go to him/her and let them know everything that you are going through. Everything. Who knows if this is alcohol related. It might be. It also could be something entirely different.
When it comes to the partying and being concerned. I think that its good to be concerned. Think about what your doing and what the long term effects could be.
I hope you call your doctor and get checked out.
