Who takes chronic doses of vitamin C OR ANY VITAMIN on an empty stomach? That's just silly.
By the way, what's silly is advocating mega dosing vitamins the way you do. You're free to mega dose all you want but openly advocating mega dosing supplements in the manner you do is the type of irresponsible behavior that will ultimately lead to the FDA intervening and supplement regulation....and not in a good way.
One person's megadose is another's standard daily dose. With Vitamin C, since many mammals make 10g a day and 10x that when injured or sick, I have no problem with taking 2-4 grams a day and more at times (Liposomal). I take vitamin E to correspond with the NASA dosages (approximate). Mostly mixed tocopherols, but some dry vitamin E tocopherol acetate and some rice rice tocotrienols as well. I've never had ANY side effects form large doses of mixed tocopherols. Carlson E Gems Elite is a good product.
The threat of removal of supplements has been around since the 80's. Nothing ever happens. They might have had a chance before it became a multi-billion dollar industry. Now, I presume, the vitamin companies have their own lobbyists. And if they don't, well, I'm available for that job! :-)
If I was in charge, I'd hire you Zorba.
