The half-drunk bottle of Sprite which started this whole Water Challenge is still in my bedroom, on the bedside table. I've kept it there as a reminder of why I've restricted myself to drinking something I've always disliked, and as a symbol of my willpower.
But today I really wanted some. I really, really wanted some. For over two hours I resisted its siren call, but the memory of that flavour wouldn't get out of my mouth.
I took a sip. One single sip, just enough for the flavour to hit my tongue. It was warm, it was flat, but it was still sweet and delicious. Then I put the lid back on and went downstairs to get a glass of water. I gulped it down in three gulps and realised that it was so much better - cooler, more refreshing and much healthier. When the glass was empty I filled it up again and it's here by my side. I'm taking frequent sips and it's making me feel better.
But I still want to drink that Sprite.
Guess my tastebuds don't care about health, huh?
