I totally feel your frustration! I've been doing lc for about 3 months and the figures have come down slowly, I didn't buy a meter straight away but when i started testing my readings were always in double figures, each week or so I would start to see occasional lower numbers, within a couple of weeks these would become the norm. Now I'm mainly in the 7''s with the occasional 6, hopefully within the next couple of weeks there will be more 6''s and the occasional 5. Just keep doing what your doing, it takes a while for your body to catch up with all your effort. (Just to let you know I'm also on 3 met a day, my initial hba1c was 112 - I'm still quite mortified about that but after 2 months on lc it was 68)
