Hi everyone I was wondering if anyone can give me any advice I'm type 2 and I'm on 1500mg of metaformin at night s/r any I had my machine yesterday and I started testing and my reading are pretty bad yesterday I did it after dinner and it read 12.0 and tonight I tested it before dinner and it was 7.0 and left it 2 hours then tested again and it came back 18.2 shock horror and it was saying underneath the reading ketone? I'm very care with my diet but I did have carbs tonight my doctor said I shouldn't test cause their was no need but I felt I needed to know myself and be more in control I don't want to bother the gp yet cause iv only just stared but I'm concerned about these reading any advice thank you
