Image: 4 panels organized in a rectangle following a sequential order like a comic strip. The first panel is of a man with a very serious face stating, "Hey man, got any diphenhydramine?" The second panel is a grainy picture of the actor Robert Downey Jr. with a slightly inquisitive face and saying, "What's that?" The third panel is an identical copy of the first image and saying, "Benadryl the allergy medicine." The fourth and final panel is a grainy picture of Bobby rolling his eyes and taking a deep breath.
Edit: Tony Start -> Robert Downey Jr. I didn't know that Tony Stark was a character Robert Downey Jr. played 🤦♂️
For allergies? Most people should start with a second generation antihistamine like Allegra or Claritin, they shouldn't cause the same sedation like Benadryl does.
If you're using benadryl for sleep, atarax can be a bit better, but if it is just sleep, I'd stop using any of them. It can be habit forming, fuck up your sleep hygiene, and long term use of anticholinergic medication may increase your risk of dementia in the long run.
This is incredibly generic advice and you should talk to your doctor about any concerns you have.
Ironically I know I just used a bunch of brand names but that's what I refer to them as off the top of my head ¯_(ツ)_/¯
