Insomnia pronounced following CT angiography

Has anyone studied possible side effect of insomnia following CT angiogram?  I had CT of my heart 2 weeks ago and
find that I am wide awake 3-4 hours after I have fallen asleep. My CT results were essentially normal so I don't think
stress related to scan would be causing increased insomnia.


This discussion is related to heart CT scan contrast dye related side effect.

maybe a reaction to the dye?

there is even a related link added to your post, which mentions the dye. Does anybody know if a computer or a person adds those links?

After a Head CT, I have a "high pitch noise in my head", also I couldn't sleep the night after the scan. And, I feel myself a little different.. Its so strange..

Any help?
