Accidentally took lorazepam after drinking

I’ve just been out to dinner with friends, had a soju before dinner at around 6:30, friend bought me a shot at dinner around 7:30, then had a cruiser at karaoke around 11:30. Got home around 12:15 and knew I needed a good night sleep so took a 1mg lorazepam without thinking. Felt completely sober by the time I took it but still kinda worried
