Hey Cynic. Tough call.
Sounds like you've done the reading and are making sensible choices (bet that sucks!). As you said, once you've adapted to the new regime you will feel a lot better so just hold on in there. There is lots of sensible advice out there, just learn to trust what the ingredients say, rather than the 'low sugar' sticker on the front. Oh, and advice from diabetic friends, stay away from 'diabetic' ranges of foods - they're massively overpriced and no better than any other product (that you've checked the label of!).
Go to Diabetes UK for proper advice and NEVE
