I've just passed the two year mark too and I can relate to your post. I'm living pretty much a normal life these days, though like you the sleep and tinnitus issues (early waking) are still present. I've heard it said that after this length of time any lingering symptoms will be permanent but I'm not so sure as I still continue to make progress with my symptoms, my sleep has become more consistent this last month, my tinnitus less too so there is hope! I know what you mean about missing your former care free life, I think we become conditioned to be 'ill' after months of dealing with PCS, it's like a residual anxiety that we have to break the cycle and dare to be happy. Yes, we can and deserve to be happy!

Re omega 3 supplements, you might want to take either fish oil or krill instead of cod liver oil as has been pointed out the high levels of vit A in cod oil isn't good.
