Yes nigel it seems a bit low and I can go into a low 3 and still function normally, after talking this over with the diabetic doc he agreed with me that because lower readings my body could function ok at this level, I have to test often but this isn't a problem, i've been type 1 for 43 years and feel great, for most diabetics our quality of life is down to us, I'll work hard on my control until that cure arrives. Good luck and health to you all. Phil
