I bruised my heel too (I am a skateboarder, I definitely know about heel bruising..haha) just recently and they do take forever to heal. The only thing you can do is wait it out, and get some padded insoles or gel insoles to prevent from hurting them further.

I have the same thing and I have a heavyweight gi, but of course it stays in place more htan a lightweight..but my lightweight did good as well, it moved all the time, it's totally normal. Try tying those knots TIGHT.
Hmm...I don't know much about supplements..I do drink though a power shake and it does contain extremely good stuff in it, 1 glass of it will replace a daily multivitamin...and full of energy. It works..it's called "powershake"..maybe check on that? As for the supplements, you could just google that...
Unless ya stepped outside and got nailed by a car then walked away then a vicious dog down the road attacked you and you were lifeflighted then your helicopter crashed....but maybe that'd be something for real tv...then you wouldn't have that much time, but until then..we do...
If you're fighting, and you get a sensory overload, what will happen? You will either stop, or you won't think clearly..not the best thing to have happen while in a conflict.
Hey, I'm just wondering how many people really know this kata...I can never seem to find anybdy that knows this kata well..I learned it at karate camp and found it to be one of the funnest katas out there.
