I am a word of five letters and people eat me. If you remove the first letter, I become a form of energy. Remove the first two and I’m needed to live. Scramble the last three and you can drink me. What am I? No use of reference material or the internet of course to ensure fair play. Good luck.
NO POSTS - instead you PM me with your guesses any time up to 5am tomorrow and we'll see how can get it.
