Moy, the best thing really is bedrest, plenty of fluids (water) and paracetamol.
Also a good dose of vitamins C, D and the B's
The more you try to just 'be normal' the longer it will take to recover.
Concerning the Vicks Rub on your chest..... they don't call me 'Warm hand Terpe' for nothing.

Give me a call
