Sorry to hear you're feeling ill.

I do much the same, although TBH since I quit work I haven't got sick, funny that!

Having said that I did feel a bit wiped out yesterday a.m., but I still got up and did my park run, then slept for a couple of hours and then got a good 10 hours last night!

I feel much better now, so sleep, almost certainly the most important thing!

Get well soon!
