I have the same feeling. I’m very sensitive to pseudoephedrine jitters and do my best to avoid it. It may be placebo, but phenylephrine “works” for me and can “tell” days that I forget to take one in the morning when I have post nasal drip. Knowing it should have no clinical effect, I’d be interested in blinding myself to a placebo to convince myself it really has no effect.
