I had my doubts when I heard that NyQuil/DayQuil were changing their formulas to remove pseudoephedrine. But now that I’ve been slightly under the weather for a couple of days and taking the new version of DayQuil which uses Phenylephrine HCl as a decongestant, I have to say, I was so wrong. The new ingredient works great for me, and it doesn’t have the side effects of completely drying out my mouth and making me feel light-headed. Now, not all is well. Lisa says it doesn’t seem to work as well for her, so it may not be for everyone. But for me, it’s a big improvement, and I’m glad I was wrong.
