Drinking on an anti-depressant?

So I’ve been on this medication for almost 2 months. I haven’t drank at all because I’ve heard the worst could happen. I’ve also heard people say it doesn’t affect them. I know you technically aren’t supposed to but a group of girlfriends and I are going out for mexican tonight and I’m just really craving a margarita. Would one hurt? Does anyone have any experience being on this medicine? I don’t plan to start drinking every day or have more than one, but I just want to ask if anyone knows anything.
