Like livacreature, I am type 1 diabetic.
This is my second pregnancy. My first was a healthy pregnancy, no complications, but birth was a trainwreck -- c/s after a long and complicated induced labour. I also found the 'something terrible could happen AT ANY MOMENT' attitude during pregnancy totally exhausting, not to mention the enormous amount of time I spent in appointments, making sure that everything still looked a-ok.
I'm finding it a lot easier the second time round so far. I test a ton, adjust my basals and ratios, and while it's definitely a lot of work, I knew what to expect so it isn't quite the shock it was the first time. I'm also in a different place in my life, and less naive about how the health system works. For my first, I was still a fairly new grad student and just getting started in medical research. Now I'm done my phd and my area of research gives me more insight into medical risk than I had the first time, which I expect will make for slightly easier conversations with health care providers.
livacreature, that (nighttime high followed by a crash) happens to me if I eat anytime in the two-three hours before bed. I just don't do that when pregnant and it makes life a lot easier. A little big of cheese, eggs, nuts, veg, etc. work fine (you know the drill), but nothing that requires a bolus, make sure overnight basals are tuned well, and voila, no problems and no sleep disturbance.
