@872ab8e1 I've seen so many terrible headlines for this decision that don't differentiate between pseudoephedrine-Sudafed and Sudafed PE or Benadryl vs.Benadryl + Sinus Congestion. 

Still, phenylephrine hasn't been effective for me, ever. And I just keep a 6 months supply of pseudoephedrine around for when I need to stop a cold before the (otherwise inevitable for me) ear infection sets in.
