blood sugar after 20mins

how many ml in your quarter glass ?
my guess would be that you had about 20 grams carb in your lucozade glass ?

i realise it can be hard to measure how much you are drinking if feeling hypo --
but nobody can realistically know what you have consumed if you don't either so perhaps get a glass and stick some tape on the

side or some nail varnish ( whatever is handy ) at a pre measured point and just use that glass for hypo treatment and you can poutr to the premeasured

line in the future so you will know how much carb you are consuming
