I hear you, and agree! The pseudo-pseudoephedrine that they let you buy without the third degree is a a placebo with uncomfortable side effects - I guess they threw in the stuff that makes you feel worse so you think it's doing something.
I have to take that pseudoephedrine and guaifenesin every day to avoid ear infections, and be able to breathe through my allergies when I sleep. The fake stuff doesn't do the job, at all. I used to get the combo in a long acting cheap, by prescription, and in a 90 day supply. Then Mucinex bribed the FDA to let them, but only them, sell guaifenesin extended release OTC, and suddenly my costs went up 10x, then PSE went to the "sign for only a 10 day supply" and my costs doubled again. What I used to get for $30 is now $150. A rip off in the name of patents and the "War On (some) Drugs".
