0.25 xanax and alcohol

Is it okay if I take a 0.25 xanax if I am planning on drinking in 10-11 hours? I always get so nervous about mixing the two. I have a pretty low tolerance to alcohol (i’m assuming, after college graduation i did 75 days sober and tomorrow is my first night back out) I am having bad anxiety and trouble sleeping because of it. Thanks!
