@Chumly,
Sorry to hear this, Chumly.
I know what a pain-in-the-ass you are when you are feeling chipper; can’t even imagine what you are like when under the weather!
I cannot take cold medicines (they knock me out almost immediately)…but I understand they can bring relief…or at least, the semblance of relief.
From what my wife tells me…take cold tablets for a week…and you will start feeling better at the end of the week. Alternatively, you can forget about the tablets and wait for a week…and you will start feeling better anyway.
Apparently “the week” is the essential ingredient.
