"diabetic" foods are NOT low carb. They are not really that suitable for Diabetics to be honest (coming up on my 7th year as type 1). The foods are often pumped with synthetic sugars and alcohol sugars. Low carbing in the UK is difficult as SIN. I was raised in the USA and there is SO much more choice and the food quite frankly just tastes way more appetizing out there. I bring suitcases full of food into the UK every time I'm over in the states. Things like cereals (chex, plain cheerios etc), granola bars, salad dressing mixes, vita tops etc etc.
I think the best way you can go is to get something like a George Foreman grill and make things like grilled chicken or baked fish and fit in as much fresh/frozen fruit/veggies as you can. If you do get canned veggies or fruit, then rinse the contents to get rid of excess salt or sugar
I've cut out juices in favour of the extra fibre you get with eating the whole fruit. We have things like slimfast here, but they taste weird to me. Look for Müllerlight Light yogurts, Shape fat free, snack a jacks, and also labels that say "no sugar added" will usually be better for you than their normal counterparts. Try to drink water (with lemon if you like) instead of juice or soda. Even cups of tea/coffee can add lots of excess sugar to your daily carb intake.
I usually like to start my winter mornings with a bowl of oatmeal. This normally means super small portions, right? Wrong!

When you get back to the USA, you can make this breaky even better by picking up the Almond Breeze.
1/2 cup old fashioned (not instant) oats
1c Unsweetened Vanilla Almond breeze (or skimmed/fatfree milk or water)
1c water (or extra cup of milk)
Cook on stove top for 10 minutes or so, add two splenda packets (or other sweetener of choice) and some cinnamon and a dash of salt

If you didn't use the almond breeze, you can put in a bit of vanilla, but I've found the cinnamon does the job just fine

(sometimes I add a bit of canned pumpkin for a pumpkin spice oatmeal!)
Should work out to between 160 and 350 calories depending on the milk/almond breeze/water etc you use. Very good sized breakfast and keeps me going for the rest of the morning!

I know it can be a bit carby, but worth it on those freezing cold and damp mornings

And a lot of breakfast cereals have more carbs than this oatmeal recipe!
We do have Special K and shredded wheat is great too
For your chocolate cravings, I've started buying skinny cow chocolate drink mix (hot chocolate) and they also do the ice-cream bars for summer.
