My partner was diagnosed with Type 2 diabetes a couple of months ago and with the help of pills and changing his diet, exercising, not drinking and not smoking his levels have gone down from about 27 to around 10 most of the time (sorry I am new to this, so not sure exactly that means other than it is the reading on the machine he uses). He was a bad binge drinker before the diagnosis and his behaviour was manic which I assumed was the alcohol. A few days ago we had friends here and he decided to have a few glasses of wine - all fine at the time, but in the last couple of days his behaviour has been rapidly swinging from appearing very drunk to fairly normal within minutes and I know he hasn't been drinking since the other day. Does anyone have any idea what this could be about? His readings tonight were about 8 which seems fairly normal but he is not behaving normally by any standards. He is alternating between staggering about and then nodding off in the chair (peed himself) and five minutes after taking a bloody sample, he doesn't even remember doing it. I am at my wits end and don't know where to go for advice. As it's a weekend I haven't been able to ask a doctor and phoning 999 seems like an over-reaction.
