Glycemic Index? or are all carbs 'bad'?

Does anyone know or follow the GI (sp?) for their carb intake. I try to restrict my carb intake anyway. As you know though the dreaded carb snacks creep in regularly which I constantly stuggle with. I get low sugars after I've eaten certain carbs. My main diet pre wls consisted of pasta, rice & potatoes. I've cut those out to almost nil - was hard to begin with but I've got used to it and only have a very small portion occassionally. For main meals I'm ok, but am having a hard time thinking what to have for light lunches now. Whereas before wls I would have a sandwich or something similar, now I try to have protein, so usually cheese, tuna or ham (without the bread around it!!), but am bored with that now. Does anyone have any suggestions? Would a baked potato be ok if I have protein with it?

I follow both (most of the time) although we have been traveling the past week and 1/2 and it was hard, I was not always successful... I did make a low fat no sugar pumpkin pie, for me...LOL.. as my mother in law started baking cookies and everything I could not eat...LOL
