it doesn't matter what the brand name is..every since I can remember as an adult that I started a mulitvitamin, after a few days I literally get sick with flu like symptoms...I do not know why this is happening or maybe I have enough in my system and do not need to take a multivitamin.
I have the exact same problem as the OP: After 5 (or so) days of taking a multivitamin, I come down with flu-like symptoms. Swollen glands in the neck & under the jawline, that "head full of cotton" feeling, headache, even congestion & sometimes a cough.
It's the damnedest thing. I've never heard of anyone having the same problem until now. My doctor has no idea what I'm talking about when I explain it to him.
So instead I take a C + B-complex vitamin with no problems.
