Sick of the gestational diabetes diet

Is anyone else getting frustrated with not being able to eat the things you want? I've been on this diet for 4 weeks now and I'm craving sweets so badly 😫 I'm so sick of veggies and toast and peanut butter and eggs... Etc. I saw someone posted they have to keep their sugar under 180... I have to keep mine under 140.. It's usually between 90 and 112. What is your glucose limit?
