I test literally when I feel I need to, which is what the gp advised. So if I either feel woozy, and shaky blurry eyes and crabby mood, I know this is a low sugar level and it can be anything between the 2's and the lower 4's. Or I feel hot and sweaty really headachey and sick and I know this is high sugar level, this doesn't happen often but I bring them down with a couple of glasses of water, for the lower bloods I take glucose tablets (again on the advice if the gp). My diet is not bad, I never lose weight, but its not the worst its a middle ground I think. Ive had various random glucose tests which always come back with no worries. When I last saw the gp and she referred me to endocrinology, she said that though my bloods were in the 4's they are just about a hypo level all the time and drop very quickly. I don't let them drop to lower than a 3.7 if I can help it as soon as I feel ill I'm pricking my finger! Xx
