Robitussin Cough & Cold
Having been sick with a horrendous cold with the worst symptom being a horrendous, chest-rattling, throat-killing cough, I can tell you from firsthand experience that Robitussin Cough & Cold has done absolutely nothing for me, my two and a half year old and my ten month old (they had the pediatric versions), despite repeated dosages.
Sadly I have two full bottles (sans packaging) in my cabinet, which will now go to waste, since it’s pointless to put non-working medication into my body.

Everytime I’m remotely sick, my mom tries to drown me in that garbage.
And it doesn’t even work and it tastes like crap.
