"i have had difficulty staying asleep for several years after having open heart surgery. my doctor prescribed temazapam 15 mg. it helped some but i continued to wake up at 2 or 3 am as i had prior to having the med. only difference was i would fall back to sleep around 5 am (without the med i never fell back to sleep). doc increased to 30 mg and i slept better but still would awaken at 2 or 3 am eventually falling back to sleep. i started taking 50 mg of benadryl around midnight when i would get up to go to the bathroom. immediate success. i now sleep all night every night. 30 mg temazapam around 9 pm, usually asleep by 10 pm. take the benadryl around midnight. it works for me. been on this regimen to around one month thus far."
