Someone told me that when they took an antihistamine, they stopped producing that bothersome phlegm that you sometimes get. This person wasn’t a doctor but I did have a Claritin handy, so I decided to give it a try.
Hours later, I am definitely less phlegmy but it’s hard to say if that wouldn’t have happened without the pill anyways. This isn’t something I’ll try very often but it was an interesting experiment.
