I have to say that surely when you are in a restaurant you have to ''guesstimate' your carbs? Or do you never eat out?
To me thats the same as eating in hospital or anywhere you might be away form home?
I certainly dont carry a set of scales around with me, and we've always done alright. And if we do tend to underestimate the amount of insulin req'd ( as I would rather O ran a little high, he often burns it off anyway! ) we just do a correction dose at the next meal. It aint rocket science, is it??! 🙂
