Vytorin and newborn baby

I do not know how long I am taking Vytorin, maybe a year or so. The doctors called me and whooped it up ( I thought it was a serious issue) but they were just so excited that my cholesterol levels and other levels went down by more than one hundred points. I am now investigating sleep maintenance i.e. I go to sleep and wake up many times during the night and then go back again. This never happened before. It is like I have a newborn baby. Besides that I am tired all the time and later in the day I want to nap, i.e. I feel bone tired and it is more like I am sick. I took this all into the idea of aging but I am beginning to look into my drugs that I am taking. Just read that Zocor has effect on sleep and Vytorin has Zocor in it.
