Temporarily out of action

I have been temporarily out of posting action due to illness, I picked up a horrible bug over the weekend and its been a tough/long few days of going through the motions of taking medicine and resting. I wonder sometimes when I am ill, whether I caught the illness or the length of it, if its due to some deficiencies in my diet. Its more than likely, but I do try take vitamins supplements but have not seen any real benefits.
