Throwaway post: I have the flu (even worse, the man-flu!). It occured to me that it feels very much like... hangovers as I remember them. Ironically, I also don't feel my feet in this situation (I would give it a 1 on the pain scale). Rather odd, as it seems to amplify other niggles.
Anyway, I can live with feeling crappy for 3 days. I don't think, nah, make that: I'm very sure I don't, could ever again live with feeling like this every morning. On topic after all.
