Wow - that happened to me, too. I didn't relate it to a change in lifestyle, but maybe that's so. I blamed it on my cat! My nose would stuff up, completely at night and I had to resort to that gross nasal crap - and I avoid meds, so that sucked. I'm around week 7 and noticed just last week that it subsided. It could be the season - I don't know about OH, but here in CA my allergies went CRAZY this past month.
