Hello!
I am curious. What is your usual remedy for cough ( painful, green-grey slime ) and cold, no fever. This is what I am suffering from at the moment. 
I prefer to drink as much as possible.
F.P.
Guiness.
I usually take some antihistamines at the onset of symptoms which stops mucus production. You might have to try a few varieties because their effectiveness varies from person to person.
Flue/cold: a dish with an onion cut into little pieces.
Sore throat: fresh lemon juice, hot water (like tea) with honey
And sliced onion in damp cloth around your neck with scarf or something similar.
Of course, Vitamine C helps, and drinking a lot of waterâŚ
For the rest, sleep will help too
/me is not the person to take medicine, unless precribed by doctorâŚso far only after surgery for me
When I get sick, I usually drink as much Cranberry Juice as possible. Usually about 128 oz each day. Of course, Cran-Raspberry Juice is ok too. 
I would go for juice low in sugar, since so much sugar in such a short time makes my stomach feel queasy, but thatâs just me because I donât normally consume a lot of sugar. Nevertheless, this remedy works well for me.
