Ativan would be a good choice for helping sleep. Its effects last 2-4 hours so it would be mostly out of your system the next day.
The 2mg are the best and most effective for extreme anxiety and
night wrestling. All benzos can be addictive if your body adopts the med instead of its own processes for initiating sleep or controling anxiety. DO NOT MIX WITH ALCOHOL. YOU'LL GET BLACK OUTS AND SERIOUS SHORT TERM MEMORY LOSS. ONLY USE ONCE IN A GREAT WHILE WHEN YOUVE BECOME EXHAUSTED FROM DEALING WITH NOT SLEEPIN FOR SEVERAL DAYS. Practice mind relaxation techniques when you lay down on your back and focus on a wake dream that relaxes or involves you. The sleep will come.
