Vytorin and lexapro

I have been on Lexapro for several years to help with migraine auras brought on by anxiety.
6 months ago my doctor put me on Vitorin for my high cholesterol (280 total) which was not being controlled with Lipitor. Lately I have been having the auras again and thought maybe the Lexapro had stopped working.
I also have a problem sleeping straight through the night, have recently started having strong frequent urges to urinate, and some strange mental/visual experiences. e.g. I was recently in route to JFK terminal and I swore that a sign said "Jet Blue-terminal 4". My daughter said that it was 6 but my brain literally SAW 4. She was right.
The other day I was taking a frozen dinner out of the freezer for lunch. The package said "Stouffers" and I was surprised because I didn't think I had bought Stouffers. When I went to open it it was a "Smart One" frozen meal, but I SWEAR I saw "Stouffers." I'm 54 but thought maybe I had a brain tumor or early Altsheimers or something.
I came upon this forum by mistake looking for answers. Maybe Vytorin is my problem, even though I do not experience any of the joint or muscle pain.
I need to go back to my primary physician to have the cholesterol rechecked. This better all end soon because its scaring the daylights out of me!
