Should Cerazette Be Continued In View Of Sleeping Problems?

Hi I have been on Cerazette for 6 months and having problems getting a decent nights sleep. It does not matter what time I go to bed I wake up every morning at 4am and cannot get back to sleep. Then I am tired for most of the day. I have decided to stop taking Cerazette as I long a decent nights sleep again. Can you advise if I have made the right choice?
