For the non fruit ones make them with 500 mls of water and make them hot. I find the mint choc ones the best. I only had porridge in the first week, I lasted 2 weeks on soups. Now I just drink either Choc, mint, choc, cappucino or banana shakes and everything except the banana I automatically drink hot. Plus make sure you're using an electric blender to whisk them. I can't stomach them shaken only.
Re. getting through the next few days, this is where you need to make a decision if you want to be fat any more or not. Nothing else will do it. Think of it like quitting smoking. It's only yourself and your willpower that will get you through it. Giving up is a decision you make, there are no contributing factors. Excused are just smoke and mirrors. If you want this you can have it. Every single person on here will reiterate that this diet works 100% of the time when you stick to it.
Best of luck and you should be proud of yourself for getting to Day 3 already, now make sure you get to day 6.
