I am flying for a weekend away to vegas. i am very afraid to fly and have been given lorazepam. if i take it at 2pm can i have a drink when i arrive approx. 11 hours later or should i wait until the next day?

Never. Alcohol is a poison that never did anybody any good, ever, so stay away from it. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
