You know how alphas go mad because of omega pheromones and we see scenes of them really wanting to bite the neck because of instincts (bite their hands instead because LOVE)... why can't they just plug their noses? Just pinch them closed?
If they simply did that and breathed through their mouths, wouldn't it be completely fine albeit uncomfortable?
I can't believe I've never thought of this. Thinking back on all the omegaverse I've read, I can't think of anything that would clash with this theory.
Maybe the argument would be that once they get a whiff, they go crazy, but wouldn't it make sense that if they had enough self control to bite their hand and endure, it'd be even easier if they didn't continuously inhale omega pheromones? Maybe it's not foolproof, but I imagine it'd help a LOT.
