Afternoon. I'm T2 and was diagnosed with shingles 2 weeks ago. I've been feeling tired, generally unwell and was sick yesterday. The doctor checked my urine and found ketones. His advice was to drink more and not just water- to drink more sugary drinks which I avoid as I'm T2. He said the ketone reading was 4. I've come away feeling a bit confused and have tried to find out more online but I'm no clearer! Can anyone give me advice on this? Thank you.
