xanax after alcohol

How dangerous is it to take 1mg xanax after 1 bottle (litre) of vodka? I’ve been searching here but there are basically only answers for smaller amounts, Im probably gonna finish the bottle in the next hour or so and how safe (generally) is to take 1mg xanax couple of hours after I finish the bottle? I don’t know if it affects it but I have adhd and a pretty high tolerance to alcohol, relatively new to xanax only taken it couple of times and all has been in the last week
