Seattlejo, you are SO right...it's frustrating to read all those labels and it really is better to eat less processed food! I actually eat organic yogurt with a dollop of SF jam and a packet of Splenda, along with a sprinkle of cinnamon (it helps you avoid Type II diabetes). Sometimes I eat packaged yogurt...like the Light Activia, or some of the light yogurts...but you really have to read the labels carefully.
The more time you spend in P2, the more you'll build an arsenal of things you can 'grab and go' that are SBD safe.
In the meantime, try your hardest to plan ahead and have a 'Plan B' in your car if things don't work out. Like soy nuts, a piece of fruit, or a cheese stick you throw in your bag/purse.
You can do this...good for you on throwing away that protein bar!
For those of you who live near them...there are these great convenience stores in PA that have awesome SBD snacks like hard-boiled eggs, cottage cheese, single-pack cheesesticks, fresh fruit, etc. Just keep looking around and you'll find places you can go when you need something and didn't get a chance to plan ahead.
Frustrated!
and something I was oblivious to just 5 months ago. I have found it in "healthy" vinegar based salad dressing, yogurt, most bread & cereal, to name a few. I have read every bread label at the grocery store - I now make it a point to avoid HFCS, even if it means choosing a bread with a natural sugar far down on the list. Tried to find a hamburger bun 
that would work (far better to make it at home than to give into fast food) and was actually unable to on the bread isle. DH found pumpernickel in the bakery isle and we bought those - but it just should not be that challenging!
