no, its not safe. anytime you mix a benzo (which is the Etizolam in situation) w/ alcohol you are asking for trouble.
I am surprised no one else jumped at this.
the benzos and gaba are something I take regularly myself, but why do you need the gaba at this point? you are already taking a benzo? I use it for an anti-seizure drug, but not just to get "high". who knows, maybe you are using it as a pain killer or another reason, but if not needed, dont take, if you do, then by all means, go ahead and mix those 2 drugs.
I would surely leave the alcohol out if you could; 1 glass of wine after work would be OK but even that would put you in a bit more of sedation becuase of the benzo you have taken; benzos and alcohol are one of the worst mixes there are and are 2 of the worst withdrawals you could possibly imagine, so please be careful.
good luck.
