Alcohol and benzos ( or Etiz ) are not things that you should be combining on a regular basis, as dependence both physically and mentally can be very unpleasant and difficult to resolve.
I'd avoid benzos more than 1 day a week and then keep the dosing low, if it's not working skip a week, tolerance is a bitch with this stuff and doing higher doses will lead to a steeper climb up the tolerance ladder.
You might want to think about why you are feeling the need to take these things in that way, if your so unhappy or stressed you feel the need to escape it may be time to discuss this with a doctor, if not knock it on the head and save them for special occasions.
