advice to Jack Osbourne

Hit up hard on mega doses of full spec oils (use pharma grade fish oils).
Same for vit D3: huge doses, then stay at 16,000 units. (Test blood. Forget the studies of D2. D3 is "food" so pharma will ignore it. Interferon? Um. Please. Read the studies carefully.)
Keep exercising. MS is like a vandal on a bridge you have to keep painting so it won't rust. Everyone's nervous system is breaking down and replacing itself everyday, anyway. You just keep ahead of it.
Fear not. Being upset helps the vandals.
Copaxone makes sense. And giving yourself a shot everyday talks to your unconscious: we can do this, buddy!
Eat REALLY well. Cut sugar and flour and all prepped food.
Don't take the steroids.
Probiotics!
Be in your heart. There is no distance between us.
