Had double pypass surgery in November '07. I'm 61 years old. All went very well, no heart attacks prior or to date. While at the hospital I was put on Vytorin. Never thought much about it until recently I started experiencing insomnia. Not mild...I'm talking about up until 5 a.m. then it would subside. Finally the light came on. I have stopped taking Vytorin and have requested my doctor find an alternative. I have had other symptoms that I now can attribute to Vytorin. From what I understand it could take months to get out of my system. Any comments?
