Hi there. I'm prediabetic and I have been working so hard to control my levels since May. I have lost weight naturally, dropped 2 dress sizes (18 to 14) and working hard at my low carb meals. I have recently had a week's holiday in Tenerife. Sun, pool, walks and sensible eating. My levels were fantastic. Spanish tapas - high protein and veg - really suited me. For the first time I managed to get my early morning levels to 4.9, 5.1 and never above 5.5. Brill! I'm now back at work in uk and I'm struggling to get my levels below 6.0. Normal at other times of day. Had more indulgences in Tenerife than I ever have at home. So what is it? Stress? Climate?
