Had a beer at 1-2pm , took .5 mg of lorazopam at 11pm and im i gonna be okay. still awake with anxiety at 2am. what should i do?

Do not believe that one beer and low dose lorazepam 9 hrs later pose any threat whatsoever. However, your anxiety appears to be associated with insomnia, and this needs to be addressed. Would stop your lorazepam, which likely is losing efficacy due to tolerance. Address your anxiety with cognitive-behavioral therapy, start a sleep hygiene program.
