My dr felt presc sleep meds weren't the choice for me. so i've been taking 100mg diphenhydramine/nightly for 3 yrs. should i continue to take the otc?

Better Sleep Hygiene: Try better sleep habits before relying on meds. Maintain regular sleep schedule, do not force sleep, avoid caffeine beverages after lunch, avoid alcohol near bedtime, avoid smoking or other nicotine products, adjust bedroom environment to decrease stimuli (reduce ambient light, turn off television), avoid prolonged use of light-emitting screens before bedtime (laptops, tablets), reduce stress.
