How can i stop the smell of beer

I wanted to try drinking at collage for the first time, im trying not to make it obvious while drinking and after. If i pour canned beer into a metal water bottle, what are the best ways to deal with the smell during and after drinking it?

Im mainly concerned about my breath amd any smell that might stay in the room is there anyways to cover that smell up? Just looking for advice from people with experience. Thanks.
