Ketones are fine so long as you are not on Insulin. ketones in the self are not a problem but when high ketones are present with raised blood glucose, the Ketone levels can get dangerously high and T1 diabetics can get Ketoacidosis which can be life threatening.
Going cold turkey on carbs has obviously done amazing things for your blood glucose (good) but for this to be sustainable and healthy you need some veggies to take your carbs up to about 20g a day, and increase the nutrients you are getting. I see you are eating salad, so your carbs won't be 1g. Have salad with your lunch, add a tomato and half an avocado. Add green veg to your dinner, have any sort of above ground green veg, cabbage, cauliflower, broccoli, spinach, Swiss chard etc etc. that will probably take your carbs to about 20. When your blood sugar is stable and you are ready to vary your diet more, whenever you eat a new more carby food, check your BG 1 hr and 2hrs after and anything that spikes you too much, eliminate.
Add some salt to your diet, drinking a cup of oxo or similar twice a day will help with the nausea / low carb flu, and make sure you drink plenty of clear fluids. The diet is a natural diuretic so you will lose more salt and water in your pee, until you are fully adjusted to it. In the medium to long term, your medication is likely to need to be lowered.
Good luck.
