Do any medications that you take for a cold or allergies either 1. interfere with your current meds, or 2. cause you to feel manicky or more depressed?

I noticed that taking Zyrtec D (not regular zyrtec), Allergra D, Sudafed, or any kind of decongestant speeds me up a lot. If I am already feeling manic or hypomanic, it makes it even worse. I think I'm super sensitive to these meds, but they tend to be the only thing that works for my chronic sins problems. Come to think of it, I'm sensitive to any kind of stimulant.

I didn't even think to ask my pdoc if any of these meds interfere with my psych meds, although I doubt it. What's your experience?
