As much as it pained me, I tried to stay away from coffee too, especially with milk. Drank a lot of herb teas and stuff with lemon.
Tadin's Bronco Te and
Ginger Tea were awesome and helpful. Ginger is very good for ya...
(I got those teas from my local Mexican store, unsure who else carries them)
For me I also doubled up on vitamin C with rose hips...1000mg a day. And, ate a raw garlic clove a day too.
Not very sociable I know, but it's a powerful natural antibiotic along with the ginger.
The hot chiles I normally eat didn't hurt to clear the head either. Kill the cold, not your immune system, I say.
When needed, I did take some cheap meds from Dollar Tree too...same stuff as the $$ ones, just a buck each.
I only took about half the dosage though. That Guaifenesin is a godsend for getting the phlegm out.
