Alcohol and adhd meds?

Hello, so I just started collage, and am in the process of rushing a fraternity. I’ve been drinking a lot the past week or so, much much more then ever before, but I’m still taking daily ADHD meds. 72mg of , to be exact. I’ve heard that combining adhd meds with alcohol isn’t the best idea, but does anyone here know how bad of an idea this really is?
