That's interesting 'cos recently I've been feeling completely exhausted, sometimes to the point where even socializing isn't really possible. How will too much sugar affect the body like this?

I put an average amount of sugar because it's not a great deal more than what most people have, or what I've been used to over the past few years. Although I know not to use that as a guideline or indicator that I'm getting too much.

An average day's sugar intake would be:

Breakfast:

1 teaspoon honey in porridge
2 teaspoons demerera sugar in porridge
250ml innocent smoothie (made up entirely of blended fruit)

Rest of the day:

honey sandwich
apple
orange/plum/grapefruit whichever i have
sometimes a chocolate bar or a few biscuits

Of course there's sugar in my other meals as well but they're the only really sugary foods I eat on a daily basis. Does this seem like a lot? I don't drink tea or soft drinks when I'm at home, only water. If I'm out for the night though I'll have several cokes. I'd normally drink a lager but at the moment anything alcoholic irritates my quad tendons. They get inflamed whenever the blood flow increases, so I've also been showering in warm water to reduce the inflammation a little bit.

For the next few weeks though, I'll reduce my sugar intake wherever I can. I'll start with the honey sandwiches, biscuits and chocolate and see whether that affects anything.

I'd like it if the answer was something as 'simple' as diet, but the frustrating thing is I'm unlikely to ever find out what the cause is for me. If I do start to feel better it could be because of the ice massages, iron tablets, red meat, vitamin B tablets, stretching, trigger point therapy, more exercise, better sleep, yoga, etc, etc.
