I got diagnosed this week and have been told to cut my carb intake. The one thing I have noticed is the headaches in a morning, somedays it feels as bad as a borderline migraine or a very bad hangover. I cant think straight and I feel awful. I have got a blood monitor for my sugars and before I go to bed I test them most nights I'm in low to mid double figures(got an appointment to see a nurse on Monday) so I'm only using diet to control my diabetes. Is the headache something I need to worry about? oh and I test my sugars first thing as well and still high, somedays higher than when I go to bed.
