Alcohol (i think) related heart problems

So im 27, and recently have been quite concerned about my binge drinking which ive been doing since around 19/20 ish.  I guess I would catergorize myself as an extreme binger.  LIke throughout  college I would always function fine and do my school work during the week without needing to drink but when thurs/friday/sat came around i would always drink with buddies and often blackout.  This has continued over the years.  I often though binge now not out, but ill get a couple of bottles of wine one night solo-then wake up and continue on that binge.  Just recently I kind of went on a 4 day binger where one night i remember having 3 bottles of wine and dont remember anything after that.  After these binges go down I often go through I guess the withdrawal stage.  This is where I'm concerned. I've been reading up on my withdrawal symptoms and am worried.  I experience the normal stuff like weird sleeping patterns/insomnia, lack of energy, some numbness and "tingling" throughout my body, random muscle convulsions in different places where it looks like theres like like something beating under certain areas, um, heart palpitations, and I finding myself taking lots of deep breathes with a lot of pressure in my mid back -like the area where the heart would be. Usually after like a few days of the lessening of these symptoms im back to normal-go to the gym 3/4 days a week-weigh about avg for my height 6-2 185.  I do usually 15-20 minutes of pretty extreme cardio fitness after lifting weights when i go.  Usually feel fine, tho see my pulse can get way up to about 180 sometimes , i do go very hard though cardio wise for shorter periods of time, pushing myself.  I also think my normal resting pace is usually only around 48-55 which i know is very low.  It seems going from a low resting heart rate to 180 seems abnormal.  

I guess I've come to a point and am acknowledging that these are not normal hangover symptoms and the heart symptoms are really worrying me.  So, I guess Im just interested to see if I could indeed have some form of alcoholic cardiomyopathy or something else.  Because it is odd i can just go back to working out fine without any pains or palpitations after i do cardio workouts, after a few days after i stop binge drinkin.  I guess I've become light headed before if i really push it for like 20 mins, but usually no palpitations or pain or anything-just normal cool down.  Im going to seriously look to stop drinking completely for awhile and see how i feel, and hopefully permanently after that.   These symptoms have been around for quite some time obviously to different affects depending if i have just like a one night binger or it goes on for 2/3 days. I dont smoke by the way.  Thanks a ton for the help
