Hi Cyn -
I do exactly as the previous poster - I track everything individually, or settle on something as a 'meal' and then enter that (and hardly ever change it the next time I have it!)... so, there is a LOT of entering info in the early stages, but it pays off. So, for example, if I am having a sandwich, I will enter for lunch: the bread (2 slices), the turkey (and weigh it), the spread, the lettuce... and then if I have that again, say, two days later, I can just copy it over. I did find the entering quite time consuming, but honestly worth it

'Guess work' just doesn't work for me - I learned this the hard way with peanut butter - what *I* thought was a tablespoon on my knife coming out of the jar was actually TWO!
I have changed my eating habits tremendously, but at first, I didn't worry about sodium and fat and sugar and such - I just counted calories. As time went on, I started making different choices; for example, instead of a Lean Cuisine (which is not a WHOLE lot of food

but a lot of sodium) I started having a grilled chicken breast, couscous and salad - a HUGE meal for the same calories and less sodium.
I cannot stress enough how gradual those changes were, for me. On my birthday in May, I went to the Dairy Queen and had one of those waffle sundaes (the nutritional info is on their website) - now, I wouldn't dream of spending half my day's calories on that, but back then I didn't worry about sugar and such. It is all about small steps.
Good luck!
Heather
PS - OOPS! Realized you probably didn't mean me - how arrogant of me!
