Sultanas, yes! I have those in a jar for smoothies, never thought of putting into Weetabix.
Never met anyone who has any cereal with water, to be honest milk is tasteless anyway largely, but milk has texture/thickness which water does not so I can't imagine how flimsy watered cereal must taste
It's popular enough in every office I've worked go have both water and milk versions.Some make porridge with just water too. It's horrid.
Calorie load in the morning!I do half and half. Save the calories that way and tastes fine. I did try just water but the texture wasn't right for me.
I don't eat Weetabix.
Sunflower and pumpkin seeds, some walnut pieces and milled flaxseed. Then comes the chocolate protein powder, cold milk and a teaspoon or so of deep roast crunchy peanut butter - I call it Snickerbix.
Try it. You have nothing to lose.I’m more annoyed by @Feek putting butter on his (dry!!) weetabix than I am England losing last night
