Linzy, I meant to pop in here last week when I saw your post. Sorry about that.
I know how frustrating it is when you do everything right and your levels are still high! The first morning reading is purely hormonal, so if that's high there is nothing you have done to cause that. That was my first one to need insulin for.
I ended up on insulin 3 times per day with the most being 10units before bed to keep those morning levels right, but as Sloane said bsl's do tend to calm down towards the end of pregnancy. Mine did and my insulin was reduced and I was only on a small dose at the end.

I hope you can find something a bit more interesting to eat now I couldn't eat bread, rice, most fruit so it was frustrating. I lost weight in my pregnancy simply due to not eating much for a while there I think. I was so sick of eating the same thing over and over. Because of that, insulin was a bit of relief because I could have a little bit of rice, or a toasted sandwich.

Excercise helped my levels a bit too, but by about 33 weeks I was having trouble getting around with pelvic and back pain so I didn't do much at all.

Good luck, keep us updated with how you go once you start your insulin
