Gestational - insulin

I’m almost 32 weeks and was diagnosed with GD when I was around 26-27 weeks.

I’ve been able to maintain my numbers with diet and some exercise (nothing crazy), but my fasting levels are starting to rise and they want to put me on insulin before bedtime.

Question - what is the point of continuing to diet and deprive myself (and baby) of my cravings if I’m going to be on insulin anyways?!? Like - can I start eating a bit more of what I actually want to eat and use the insulin to counteract?!? Lol I’m hormonal and I’m horrible with diets!!!
