Yep.. i was off work Thursday and Friday with the flu.. wonderful time of year it is!
Doc yesterday said the same.. water and panadol only. I know you can have certain types of Strepsils also.. the ones that dont say "Cough Lozengers" on them. They dont help that much though.
Also anything with vitamin C such as oranges, orange juice.. or honey and lemon tea is good. Unfortunately you just have to put up with it otherwise.
