Re: sinus headache from megadosing?
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?
