It's COMPLETELY Normal.

My wife and I were absolutely at each other's throats for days 2 and 3 of induction.

And we're the most low-key, non-combatant bunch of newlyweds you've ever met.

I've heard anecdotally of one or two people who found themselves permanently "irritated", but I would suggest you'll feel right-as-rain sometime between now and Day 7.
