I forgot to mention Folic Acid, Magnesium, and Acetyl L-Carnitine. I can't remember the details behind each of these, but I remember coming across them as important supplements for PCS.

If you're not sure whether you're getting enough of these vitamins, or those I mentioned in the previous post, they're all available through supplements. Depending on your diet, you'll likely need higher doses of these vitamins than the recommended daily allowance (RDA), especially B-6, B-12, C, and D.

Don't go too overboard on Vitamin D, since it's fat soluble and can build up to toxic levels in your system. I take 2,000 IU every day and haven't had any problems with toxicity, though I get very little sunlight. For B-12, I take a 500 mcg sublingual tablet that dissolves under the tongue for easy absorption (meat is the primary source of B-12, but I'm vegetarian). Alternatively, if you eat meat, a B-complex might be enough. I take a high-potency B-complex in addition to the sublingual B-12. If you get too much Niacin (one of the Bs), you can get a "Niacin flush," in which your skin becomes hot and flushed for about 20 min. It's uncomfortable, but harmless. Magnesium can cause GI issues, but Magnesium Glycinate is easier on the stomach than the other varieties (the cheap stuff is always Magnesium Oxide, which is inferior in a number of ways).

I also want to echo Eowyn's advice about taking it easy. I have also made the mistake of trying to do too much, and have set myself back as a result. I know how difficult it can be to force yourself to take down time and relax when you're used to being so active. I am one of the world's most impatient people--or at least, I used to be--and I had to force myself to start meditating to deal with anxiety problems that started 16 years ago, way before my head injury. Now, I'm having to force myself to sit for longer periods and be even more patient and calm. Even after all of my previous work meditating, it is still very hard. These days, I take long breaks about every two hours throughout the day. Even listening to audio books stresses me out after a couple of hours, and I have to go meditate or listen to relaxing music in the dark.

Finally, along with relaxing, it's a good idea to minimize sources of visual and auditory stimulation. The more you can do to avoid noisy, brightly-lit environments, the better. Even if these environments don't bother you at first, the stimulation takes a toll on your brain and eventually manifests as a worsening of symptoms.

I'm sure that none of this is easy to hear. This is a horrible condition that we on this forum are dealing with, and most of us have had to make pretty significant changes with our lifestyle to improve, and even just to keep from getting worse.

Hang in there and be strong.
