I used fish oil in high doses since recently. At first I was really enthousiastic. I suddenly wasn’t depressed anymore and didn’t have weird fears and got all sorts of things done. But the last days I started to notice that I was getting more and more hyper, with racing thoughts and all sorts of big plans, being more talkative than normally and feeling really confident (normally I have a rather low self-esteem) and being unable to sleep. It felt a bit like being on Sertraline (antidepressive med) again, at which time my psych thought I was bipolar. At that time, the “hypomania” stopped directly upon quitting Sertraline.
I decreased the dose a lot and now I’m starting to be more relaxed again (and a little more depressed).
So, my question: can fish oil in high doses (e.g. 2000-3000mg of EPA and 1200-1800mg of DHA) cause hypomania?
