    Benadryl keeps me wide awake all night long
    Anon_238530 posted:
    As the title says, whenever I take benadryl (or nighttime cold medicine), I am literally up all night. It's 2am and I am completely awake. I'm not even slightly sleepy. I actually have more energy right now than I've had all day, and I had 3 shots of espresso. About a month ago, I had really bad allergies at night, and over the course of a night I ended up taking 5 benadryl and I slept at most a total of 4 hours, and not even in a row. Does anyone else have this issue? And, yes, I did check, and none of my medicine is expired.

    It's weird, though. Caffeine makes me really really tired. It's like, if I want to go to sleep, I should drink coffee, and if I want to stay awake, I should take benadryl. It's so annoying.

    And speaking of cold medicine, does anyone else find that phenylephrine has absolutely no effect? I thought I read a recent study that phenylephrine is just about as effective at relieving pain as a placebo. I'd believe it.

    In case it's important, I'm a 21 year old female, 5'3", 115 pounds, and I don't take benadryl very often (nor do I drink anything with caffeine often).
