I have not heard of insomnia as a side effect , but it does seem a coincidence that it has been since you started taking it. Why don't you ask for a different birth control and see if that helps. Birth control can do strange things to you , I started Yaz last month after 4 yrs of not being on birth control and I broke out in hives on my face!....I have stopped that pill and am going to get a different one.
