Ha, what's your disease of the day!
Made me laugh! Don't worry about your headache, have a sip of water and a painkiller and things should be in order in a couple hours time.
Like last week I had throat sensitivity, and I mean on the outside. The whole of my neck was a little sore and sensitive. I was starting to freak out a bit but refrained from using google. All is ok with my neck this week though.
Congrats on cutting down your smoking :) Well done!
