I'm a one or two hypos a day kind of person. Usually very mild. Most of them aren't a surprise, as there are certain times of day when they are just more likely to happen. It doesn't happen every day, but quite often.
With Lantus, just before lunch, and just before the evening meal, are the most likely times. They are a bit of a nuisance, but a mild one isn't that much of an issue. I tend to have a keep my blood sugar low, and correct small hypos, policy. I just prefer that. Though that's on a good day, some days blood sugars just run higher.
However unexpected bigger hypos are another issue, then the cause has to be identified, and protective measures, against a repetition, introduced.
I've just changed to Levemir, so I don't yet know when my blood sugar low points will be, yet. But once I know, I expect to do pretty much the same thing.
