I am female and have type 1 diabetes, and my (male) partner doesn't. However, apart from one night a long time ago when he noticed me very restless in bed, tried to get some Hypostop gel (as it was called then), couldn't understand why I was resisting, so tasted it, discovered it tasted disgusting, and went to find some sweets or jam or something from elsewhere, he's never needed to help with hypoglycaemia, as usually I get to one of my many stashes of sweets before he even notices. However when he competes in adventure races, I usually marshal and drive (as he refuses to learn) and have often supplied him and his team mates with quick and long acting carbohydrate at the end of a race. My Berlingo car has 2 handy holds under the back seat floor, where I keep UHT milkshake bottles, fruit juice cartons, oatcakes, sweets etc, where they stay relatively cool, compared to rest of inside of car.
