Here are some tips that spring to mind:
1. Ensure whatever device you use to check glucose, whether it's your phone or reader, is fully charged up before you start off.
2. Ensure there is never a situation where you don't have some kind of hypo treatment on you. If you're in a group with girls, see if one of them will carry something in her handbag if you don't have enough space. I try and have two things if I go on a night out: that means if I use one up I still have a second thing just in case.
3. Start on a good level. If you have beer, or anything sugary, when it's already a bit high it's going to get worse before it gets better.
4. If you have some kind of identification to show you have diabetes, such as a tag or wristband, this is the time to wear it.
