Wonder how many people "fell" for it though.

I remember, many years ago, that I got some Antihistamine tables with Pseudoephedrine to take in 'light' emergencies for my allergies, cat hair in my case. I wasn't going to fall over like other people but have trouble breathing and a runny nose, so every time I visited people with cats, I could take one and everything was fine. When they banned it and my supply was used up, I got something with Phenylephrine and it just did... nothing. Then 5min of online research told me just as much.
