sinus headache from megadosing?

[ChrisJ]

Hello everybody,

I started taking C the other night. I took 3 grams and then three hours later, I took 4 grams. Three hours after that, I took another 3 grams. Everything was okay. The next day I did the same thing and had the worst sinus pressure/migraine that I have had in a long time. I even vomitted (gross).

Is this normal?

You are alive, so you have taken vitamin C before last night. What was your prior consumption? Why were you taking these amounts? What was wrong? What are you trying to achieve? What kind of vitamin C did you take? How long after your last dose did the sinus migraine begin?

The same thing happened to me. I started taking C to help with chronic sinus infections. I had two migraines within a couple days of each other and threw up as well--I mistook them for sinus headaches but I don't think they were. My personal theory is that I caused a temporary upset in my body chemistry by ingesting tons of C, something I'd never done before. It went away, hasn't reoccured, and neither has my sinus infection, so hang in there.
