Wow, you learn something new every day! I have been taking Benadryl for years to help me sleep, and it never occurred to me to abuse it. Good to know now that I have quit drinking and might be susceptible to a new addiction. Luckily on the few occasions I have taken a second dose in the night it didn't help, and it only made me feel worse in the morning, so I never bothered to take extra after that. I shall now make that a definite no-no.
