Hi Frenchalps. I've been type 2 for nearly two years now.
Depending on what you eat and your medication, monitor and check your levels for spikes with what food you eat. It will be a case of eat and monitor.
If you follow a good diet with exercise you can maintain your levels within the range. Generally if my levels are a little high, because I have eaten something sweet without a meal, I feel tired or dozy. If I worked too hard without eating for sometime, test to see if levels are low. I get shakey and need sugar to raise them up. This takes a couple of hours to
recover.
If you pass out people need to get you to the hospital.
As you are newly diagnosed, I would carry around your testing kit, medication and glucose/jelly babies for emergencies.
It's taken me two years to get my levels under control with a good diet, medication and exercise.
Good luck and welcome.
