It's sods law isn't it. You try and be organised and make sure everything is in place well in advance and the one thing you simply can't predict is your health.
Since coming on here and having written a thread about how to maintain your body and mind while on tour I have taken to taking one vitimin tablet (the fizz in a drink type) every day. Hopefully that is helping ward off any nasties, as I am prone to eating the wrong things and not enough friut and veg.
In the last few months I have had 2 throat infections. I'm not sure if it is escort related or not, but I never got them so often before. In the last few days I started to get a sore throat, but it hasn't amounted to anything (touch wood) and I do wonder if the extra vitamin intake helped ward it off.
It is Sunday today so I assume you are driving. Be careful, try to take your time. You can get a vitamin shot like the red bull ones at some service stations, which I find to be much more affective than the red bull ones, so maybe grab one of those if you come across them.
