Drinking and breastfeeding

So I am wondering about this because I am hearing different answers.

How many drinks can you have? my weight at the moment is 220 I am a month PP and would like to have a drink.

I have seen other moms post 1, 2 or even 4 drinks and I would be fine and I am also seeing I can drink as long as i can drive my car then i am still safe to breastfeed.

What is the correct answers just confused as to how many drinks I can really have in a night. Thank you mamas for your help! ❤
