MissJA I really know how you feel. I found it really hard to adjust, particularly when I just couldn't seem to get breakfast right.
I realised that in the morning I have to be insanely careful. I can't do cereal or normal bread, or even sausages with one slice of bread that works. Baked beans (low salt and low sugar) and eggs also pushed me over. And my usual eggs on toast with an additional low-sugar 0% fat yogart was enough to send me over!
Basically, granary, multigrain etc are all big no-nos for me. The only bread I seem to be able to tolerate is Soya and Linseed bread, which is made by Bergen (the brand I get) and Vogel. You can get them in Waitrose, and I think in other supermarkets. I can only have one piece of that in the morning, and so far I can have that with either scrambled eggs (with smoked salmon :), or with boiled eggs, or with bacon. With bacon I normally have about 5 slices of bacon heaped into my one slice sandwich.
If you are doing well for lunch and dinner, I'd say try those for breakfast and see what happens. The nurse I saw after my first week (where my breakfast readings were all between 8 and 10), said that the consultant would probably have put me on drugs, but she'd let me try the soya and linseed bread, and it worked. I had energy problems too (i.e. totally none) and so I don't really do much of the exercise after, but if you can then a short walk after breakfast might also help.
Saying that if you do need the medication lots of people do, so don't worry about it it is just your body needing a bit of extra assisance.
It is so so hard, but it does take a bit of time to sort. One thing I would say is cutting carbs completely for breakfast didn't work at all for me because it made me horribly emotional and upset.
Good luck and keep us posted.
