Alcohol and nursing

I am celebrating my birthday with friends soon. I am solely breastfeeding my 2 month old along with expressed milk. I would LOVE to enjoy a glass of wine or 2 with my friends but want to make sure I will still be able to get home and nurse. I have not had ANY alcohol so this would be my first time. I have read different things online and it is very confusing. I would like to know of any of your experiences witht this. Thank you.
