My cure kills it dead for me within a day, but I'm lucky that I seem to have a good immune system and very rarely get ill.

Basically I put the heating on early, hot meal and a couple of hot sweet drinks then go to bed as early as you can fully clothed with the heating on all night, soaked through in the morning but its nothing a shower doesnt cure, best of all virus free.

Even better if you can manage 12/13 hours kip like me
