Yeah I would be very, very careful doing that. Alcohol and benzos can be very dangerous, especially when you take them both in excess. If you're going to combine them no matter what, start off with only 1 beer or so and take it VERY slowly.
Well if you got a slight buzz than you know your tolerance is super high, so w.e maybe drink a little more next time? I don't know what you want us to say , the combo is dangerous but you know your self if your getting a slight buzz. Gouge it your self
