You should be fine considering that some studies show up to 2 drinks (12 oz of wine) per day for males is actually beneficial in cardiovascular disease. However, it is also believed that the antioxidant and polyphenols within the wines are responsible for these benefits. I guess if all else fails, just keep this in mind as a good thing to cheer ya up.
However, a drink every now and then is not gonna hurt so I wouldn't stress it big guy.
Alcohol will either be used as heat in the form of NADP or stored or used for energy in the form of NADH. In the case of it being used and stored for energy, just make sure you are NOT eating over your daily caloric intake. Try to stay away from eating any fatty food (especially trans and saturated) as they will more easily be stored as fat. Maybe a protein and vege combination might be of more benefit.
Ahhh, what the heck am I making this so difficult for...lol...just have a good time bro...you probably deserve it. Just don't get sloshed...lol.
