Need more info really Kevin. A general way to bring levels down is exercise ? However, the best thing is to discover why you are going high in the first place and prevent it. Keep a food diary and log your BG results and you may see why.
when I am testing I am between 7 and 13 on my meter. my diet is within 200-300 carbs a day. I cannot exercise at the moment due to a foot operation but will start mid Jan 14. I am on Metformin 1000mg morning and night with Gliclazide.
the one thing I have been taking is Sinutab for a bad cold I have at the moment. I thought that eating extra bits Christmas day has done this but since then I have controlled my carbs intake.
i had a bad cold recently and the chemist told me i definately wasnt allowed sinutab or anything else for that matter, it could be that, plus i agree the carbs may be reduceable if you can, the lack of exercise due to your foot op could also be pushing the blood up, so a combination of all these
