well if you take what you normally use and weigh it, you can point it by that. You do get used to guesstimating eventually. What I do is use a lil tub, measure out how much I want to budget into my day and use it throughout the day. x
didn't realise you could guess it as I thought that was a big no no in WW ... its my first day of starting tomorrow so I want to make sure I get everything right...
You can measure by the teaspoon on the eSource and OCD though I am, I do measure out a teaspoon before putting it on my toast. Portion control was a big problem with me before WW though so it's definitely my Achilles Heel.
