Does anyone have experience with fish oil causing sleep issues?

I added 1290mg of fish oil about 10 days ago. It really helped lift the foggy brain feeling, but now I've noticed my sleep pattern is all out of whack. I am sleeping 4 or 5 hours when I usually need at least 7 or 8.

I started using light therapy in the mornings about a month ago and I take a Vitamin D3 supplement. We were trying that out to see if it helped with depressive symptoms.
