Glass of wine breastfeeding??

S

I'm dying for a glass of wine. I haven't had one in 11 months now...anyway my little one is sleeling from 830 to 1 or even 3 am. So if I were to have a glass of wine around 9 would there be any concern about breastfeeding her at 1am 4hrs later? I feel guilty over wanting a drink but its been a rough day and to be honest I just want a hot bath and glass of wine.
