I am on day 2 of taking a 1 a day Spring Valley prenatal vitamin with folic acid. I don't drink caffeine anymore and get a "loopy, stoned" feeling when I do. I took them before my 3pm shift and today I have that foggy, off-focused vision feeling. I did take them with a meal as instructed.

I walk almost my entire shift and it is very physically demanding. I didn't feel this way yesterday. I'm going to maybe give it a week and then decide if I want to discontinue using them. I am prone to headaches and had a headache the last 2 days. Thoughts?
