After my concussion nearly 2 months ago, I've been suffering PCS symptoms.

So, the last 2 days, I've slept full 8 hours a night (I usually sleep 6-7 hours).

That was a very good thing to do, because when I woke up, I felt awesome! I didn't feel dizziness and headache any longer and I could finally focus. I still felt some very mild PCS symptoms, but they were so weak that it almost didn't matter!

A few hours later (yesterday), I started being anxious about something, and that brought back the PCS symptoms, sadly...

Today I woke up fine as well, but an hour ago or so I was on a bus. I was standing in the passage between chairs, and while standing the driver suddenly stopped the bus using the brake. Once that happened, I immediately was shaken quickly and powerfully in my place where I stood, and luckily I was holding in chair so I wasn't thrown backwards and didn't hit anything. Even though I didn't hit anything (only shaken by the stop), I felt very confused and dizzy immediately after this happened (I just hope that this thing doesn't count as another concussion, because it felt really bad when the bus went rapidly from driving an average-high speed to zero km/h. I also heard that a concussion can be caused from fast shaking of the body without hitting the head, so I hope this is not another concussion or a sub-concussion)...

Anyway, what do you recommend to do about that? Should I start taking supplements? I soon am planning to start taking 18 grams of Omega 3 daily for about 8 days to see how it goes. Do you recommend any other supplements to raise my tolerance for stress?

I feel like that after a good sleep my symptoms fade almost 100% and I perform extremely well, but the symptoms can be easily triggered from some psychological/physical stress. So do you guys have any recommendations for me?

Thanks,
