You could be experiencing the Somoygi effect. This is your body's way of helping you out of a low, causing a liver dump to raise your BG. Unfortunately, it doesn't know when to stop! That combined with the juice caused your BG to go too high.

When I was first put on Lantus I was told to take it once in the vening. I was having lows overnight but since I'm hypo unaware, I wouldn't wake up. I would usually still be way too low when I did wake, unlike you. I was then told to split my dose in two, taking it morning & evening 12 hours apart. That was much better although I would sometimes wake up too high. I had been playing with the split, giving more at night than in the morning but was put on a pump very soon after that. I'd suggest asking your doctor about splitting the dose. It does mean two injections vs. one but you may get better control that way.
