DayQuil did nothing

Trying DayQuil and NyQuil for the first time. Took DayQuil 2 hours ago and not an ounce of difference. I am as congested as ever with no relief. I’m hoping the NyQuil works otherwise it was a total waste of money.

No, I don't recommend this product

No relief of symptoms at all

The only reason I gave this product 2 stars is because it came in a pack with the NyQuil version which works fine but the DayQuil literally does nothing.. except maybe upset your stomach. Pseudofed works 1000 x better than DayQuil sinus.

No, I don't recommend this product
