That is correct. You know when your body reaches it's limit -- it tells you quickly quickly :)
I have been taking large doses of VitC for over 12 years. I have severe lung issues and it restored my health.
On the rare occasions I start to have flu like symptoms I ramp up my dosage. On some occasions I have taken over 150,000mg in a 24 hour period.
Any way, you have to take vitC in powdered form for such high does.
