Can't Stick with a Diet

Ok i’m probably going to get flamed pretty bad for this but i really want to try this V-Diet i’ve tried many other diets and they just keep failing and after a two week binge i’ve lost all will power and can’t stay on any diet for more then two days without going back to old habits.

so on to the question are there any alternatives to the suggested protein and supplements the V-Diet suggests preferably cheaper versions i dont have over 600 bucks to blow on this diet but would really like to give it a try. any help anyone could give me would be greatly appreciated.
