In the low 4s all last week but up to 5 this morning after a weekend away at the beach. Did have an episode last week that after a 4.2 morning reading and a breakfast of eggs I experienced an extreme instance of giddy, uncontrollable spinning head and sweating that sat me straight down on my bottom holding onto the floor in case I fell off! I'm on two 500 metformin a day. This has scared me a little about driving as it just came on with no warning and there was little I could do about it. 10 minutes later it passed and I got up and carried on at my job. Any ideas?
