I never completely tipped over. A few times, I did get way past 45 degrees and managed to clip out and put a foot down just in time. Each time, I thought I was clipped out with my foot resting on the pedal, but it was clipped back in. I had a slightly pulled muscle for a few days from the awkward recovery.

There were also a few panic situations at stops, but I got clipped out in time.

Now, after 10,000 miles, I don't have to think about it at all. When clipless was new to me, I had to plan my stops, clipping out in advance and making sure to lean that way.
