Oh, you are SO not alone. I didn't have any symptoms the first day. I had nausea and headache the second day. I had cognitive symptoms the third day. By the fourth day I really couldn't function.

You need to REST your body and your brain right now. Please take time off from everything you possibly can: work, school, family responsibilities, church. Pull in favors to get people to help you out with things.

Do you have kids? Can you have a spouse or parent take over primary care for them?

Stay in a low-stress environment. Sleep. Listen to nature sounds or spend time outdoors. Breathe deeply. Don't push your body or your brain.

Stay away from caffeine, alcohol, tobacco. Drink plenty of water (half your body weight in oz. every day -- i.e. if you weigh 100 lbs, drink 50 oz.)

Eat whole foods -- a "clean eating" diet. If you can, take 3 tbsp of ground flax seed in juice every morning.

Connect with your spiritual practice -- even something as small as making a list of 3-5 things you are grateful for every day.

Keep in touch with your doctor, and let him or her know what symptoms you are continuing to experience. Vision, hearing, and balance changes, as well as emotional and cognitive problems are all post-concussive effects that you want to have at least documented and treated if possible.

Keep us posted, too. Lots of people here have great ideas that can help you!
