Nick,

The impact could have just put you in a bad way for a bit. You need to rest somewhere secure. An old friends house is not the best. he does not know you history.

Try to find a way to rest it off.

btw, I have had some of those odd slurred speech moments. Once I was on the phone with my wife and she told me to hang up and call 911. She said I was slurring my speech. Even though the paramedics could see a problem with my speech, after a bit of oxygen and a ride to the ER, I was fine.

Be sure you are well hydrated with nutrients. Maybe you should have a bottle of Gatorade available for such times.

Did Tara hit you in anger?

Has any doctor ever done any metabolic testing? Some injured brains can struggle to get energy from fats once the available proteins and carbs are used up. MCT's (Medium Chain Triglycerides) A simple way to check this would be with a blood sugar meter. If you get spacey and your blood sugar is low, you may be struggling to get energy for your brain. Just a wild thought. Not something to worry about.

My best to you.
