I'm on day 12 and I bought a bumper pack. Tbh I don't like any of them lol but for me the best ones are the bars and soups, I drink the shakes in one mouthful I find them horrible and I've just refused to eat the mushroom soup! But the bars are okay and I don't mind the veg and tomato soups.
As said above its all a matter of choice, and it does get easier!
