Going to a friends, can I drink on Lexapro?

So I’ve been on Lexapro for nearly 3 weeks and tomorrow I am going to a friends for a football game and I’d like to drink a little. I don’t plan on getting drunk, but since I hear it lowers tolerance I wanted to know how much I can/should drink based on y’all’s experience. I’m essentially wondering if I’m gonna be floored after 1 drink lol.
