Cold sent mine up by 1 last week but I get more variation than you by the sounds of it.. could be meter noise too of course.. new box of strips?fbg and 2 hr afterwards .8 and 1 respectively but evening meal and bedtime down 1. May have/be getting a cold so that might be the issue but has followed those 3 days so puzzled as to what has triggered this - bg normally very stable could almost always paste in 3 year average and get the same result.
