I had a really bad flu a couple of months ago, including a hacking cough for about a week. May have been swine flu, my friend had it (verified by the doctor) so it may have been going round. Not had one that bad for years and years.
Time in bed and plenty of fluids, a cold is a cold, although I way mightily grateful that I'd just invested in a PSP
I find this "swine flu vaccination programme" for a virus, a virus for frack's sake, somewhat ill conceived and rather sinister.
