I used to take Nordic Naturals EPA Xtra for a long time in the past and when taking them I'd sometimes have days when my thinking was unusually fluid and clear, something I have never experienced while taking my current brand of Omega 3 (the European Moller's Omega 3 Extra). (There could definitely be other reasons too besides Omega 3 intake.)

The Sports Research Triple Strength capsules just like the Nordical Naturals have much more EPA than DHA (but the ratio is different), so I might give these a try too.

Another piece of personal anecdata related to Omega 3, is that I recently started taking most of it with dinner, and my sleep subjectively feels slightly better than when I used to take them earlier in the day.
