Im in Melbourne.. Gorgeous but cold!
With opti you need to be aware that it is a VERY low calorie diet. for 3 days you will feel shite, but if you are 100% on the game, after 3 days your body goes into ketosis and you will not feel so hungry and you will not have the cravings. Ketosis is good as it stops these, but can be hard on your liver, thats why they suggest monitoring. If you go off opti for anything, a piece of bread, spoon of sugar, chai latte, anything, you screw up the ketosis and start back to sugar and carb cravings. So go in, head down, and just do it. Opti is not for the fain hearted and not to be played with cause you will do your head in!
