[Closed] Flu recovery time ?

Made it to 50 never having had proper flu but got it for first time 3 weeks ago. Week 1 was mostly in bed, fever, mental headaches. Week 2 saw gradual improvement and a return to short hours at work, but still fever, sweats and horrid cough. Now nearing end of week 3, sweats gone, headache gone, cough and catarrh still very present. No energy though, couldn't ride a bike if I had to....

On the plus side I have lost over half a stone !

How long do these bugs generally take to clear ? Have a ride planned on Monday and would love to make it....
