Will not likely work: There is something else causing your insomnia and another 50 mg Benadryl will not likely do the trick. Instead it will just increase the intensity of any potential side effects (dry mouth, constipation etc). You will need to find out the cause (trying to problem solve, anxiety etc). If this problem persists, you will need to consult your doctor.
