Hi Mandi Jo,
To be honest, since it seems you have been following you pre-op diet well, it would probably be fine for you to have a couple drinks just for this one night...not to the point of being drunk, of course, but just to take the edge off. I don't want to be a bad influence or anything, but the again, my surgeon didn't press the alcohol issue very much. Regardless, you should do what you think is best for you. I wouldn't stress abt the party much tho, b/c you are abt to have a life-changing experience, so be excited!!
