I love bread and buy a combo of Burgen Soya and Linseed bread as its weighty and a better stomach filler it feels! Its value for insulin I think at 1.1 units perslice. The other I buy is Weightwatchers malted loaf which comes in at 0.8units per slice and is actually much nicer than it sounds! Keep an eye out for Nimble brown, again 0.8 units per slice and yummy I think (made by warburtons as is the weightwatchers) I bulk up with salads, low fat/calorie dressing such as KRAFT Light caesar salad dressing (reduced in sainsburys this week to only 26p a bottle!) and they also sell low fat chicken peices to make your salads more tasty. I am a woman of routine, every lunch I have a special K bar 1.5 units. Routine isnt MY prison (or however the phrase goes...?!?!) because part of my freedom from all this maths and weighing and tinking about diabetes all the time is to pre-pare I love to take my lunch to work and know exactly how many CPs and units I am dealing with.
I would say in the early days like these are for you, dont stress it too much. You will also find what works well for and your numbers, when you find out what catagorically goes wrong for you too! I have had this years and still cant control myself for a bag of chips from the chippy in my street! I weigh it, stare at it, sweat it over what on earth I equate it too and get it wrong every time! When I need to throw my arms up in the air and not want to do this anymore its a bar of Green and Blacks Dark 70% cocoa chocolate! I love it and the whole 100g is only 3.5 units!!
I think you sound as if you already half way there, you are thinking about what you are eating, try to go low fat and healthy and you will work it out. I had a very nice dietician at the clinic, but unfortunately know such thing existed in diabetes care until last year so only got an appointment then. I found that quite useful (but the plastic imatation food she had plated up rather disturbing!).
