For some reason I was having sneezing fits pretty bad yesterday, so I took 50mg or Diphenhydramine Hydrochloride, which is a generic
antihistamine. The sneezing stopped, I got
drowsy (this always happens when I take antihistamine), and within 30 minutes I was beginning to break out in hives.
I usually only take 25mg to combat allergies, but I just wasn't in a conciliatory mood yesterday, so I took 50mg.
