Hope your head isn't spinning too badly with all the advice, Peter! But I'll throw my two cents in anyhow. For me, a protein drink was a total life-saver. I couldn't eat much, but protein made me feel a little better, so I got a chocolate flavoured protein powder and just had it with water. It was yummy, had some vitamins and minerals in it and it made things slightly better.

Good luck! You are very sweet for posting!
