Make a cup of tea, put your jama's on and ring into work saying you stil don't feel well but may be in at lunch time. If, by 11ish, you want to go in you can, if you don't then you can ring back and say that you won't be in after all.
That's what I would do!
Generally, I work through sickness, or will do some from home, but tell myself that I need time to recouperate even if I am feeling better!! Saying that I don't really get ill very often, sounds the same as you i.e. coughs and colds, so I have never had to feel bad about pulling a sickie anyway!
Enjoy Jeremy Kyle, and make the most of trashy TV ;-)
