Dietary cholesterol symptoms and conditions

i have been on vytorin 10/10 for 2 yrs.Last year i started having multiple symptoms.Nausea,loss of appetite,virtigo,and now anxiety issues.i have been to cardiologist,ear doctor, neurologist,eye doctor, and had many tests and they all come back normal. I have concluded it is the vytorin maybe?i stopped 3 weeks ago and haven't felt this good in months.my energy is up and im starting to feel like my old self again.my doctor wants me to go 3 months on no meds to see what happens.at that time id like to try omega 3 and red yeast ice? anybody had good results with any of these? im 51 and in great health other than cholesterol of 250.
