Anecdotally, I've read a long time ago that fish oil should help with sleep but I didn't start supplementing. Fast forward to this summer, I had big sleep problems, I couldn't keep a normal schedule and when I woke up I had terrible brain fog, took my like 2-3h in the morning to wake up properly and be able to function.
Then I started taking fish oil, I got it by the bottle because I've read pills could have rancid oil and I figured if I directly taste it I will know if it's fresh/well kept.
I put like 5-10ml in a shot glass and fill the rest with water, just chug it and rinse the glass with water a few times. This way, I can barely taste it and have no fish oil aftertaste, the flavor they add might help too

My sleep problems disappeared overnight.
