I drink to get drunk, read the rest and tell me if it’s normal pleaseeeee

At friends houses and party’s I pull out pint glass fill it just under the top with vodka gin and whiskey then a bit of juice to dilute it. I drink all of that and then that’s it. Is this too much to drink or is it average or a small “ dose “ if you will and how do I drink it without feeling like I’m going to vomit every sip and for the duration of me being “ drunk “
