Given that the director has given some guidelines at last on where they're going with their werewolves, it is safe to say your idea is closer to the filmmakers' than a purely supernatural origin. At the time I wrote it, though, it was up in the air.The reason I'm suggesting a shift be a conscious (or unconscious) decision is because it'd be a lot easier for the director to attribute the shift to a 'lycanthropy bactirium' reacting to electronic nerve impulses recieved by the brain, than to try and explain why the full moon or the three-per-month planner has anything to do with it. If you want to add some restrictions to the nerve-impulse theory, here you go: "shape-shifting hurts."
Scientific or supernatural, it doesn't matter. A character who changes into a monster when stressed out is a character who changes into a monster when stressed out. Comparing the two is an analogy, and NO analogy is perfect. If it was, it wouldn't be an analogy, it's be the same thing.And while I'll admit your comparrison of a werewolf to a lame Marvel Comics hero was effective, it should be noted that the canned peas mascot has his powers explained from a scientific perspective. Lame, yes, but if you're going to lecture the use of magic, don't do so by comparring it to a character that was created via the alternative.

Backing off from this incipient flamewar, let's get back to the subject. What a human werewolf would be like.
It's probably safe to say some things would carry over from their werewolf life. Fleas and ticks and other parasites would be a problem, for one thing. Imagine having to walk into a pet store for enough flea bath to use on a person, and having to do it with fair regularity!
Territoriality would likely be an issue, but I doubt they'd have more than momentary urges to pee on the houseplants or in the corners of their work cubicle. But they would feel anxious and stressed if someone entered their space that they didn't expect or invite. Boss entering the cubicle without pausing at the entry would be a major irritant.
They would also be protective of their mate, if any. I seem to recal wolves being akin to humans, in that they try to stick with one mate for life but don't always succeed (and I don't mean because the mate died). I could be wrong in that, but I do definitely remember a nature documentary where the omega male actually seduced the alpha female, which made the alpha male very pissed indeed. So weres would probably tend to be very jealous lovers.
Chocolate may or may not be an issue. It's been announced that weres heal faster than normal even while human, though not as fast as at other times. Chocolate contains what is essentially poison for dogs, but I suspect a reasonable dose - a single chocolate bar, for instance, or a bowl of Cocoa Pebbles - could be dealt with by the virus. On the other hand, would a werewolf want to risk it? They might avoid it as one of those "just in case" type of things. Might make for an interesting scene where one werewolf tells another it's okay, though, and the second is very reluctant to disbelieve.
I see weres as running the gamut, physically. They might be strong, or weak, or nerdy, or fat... whatever. I think all of them would have higher endurance than you'd expect by looking at them. The fat were would still lag far behind the fit one, but he'd run faster and for longer than you'd expect a fat person to run. Looking at his time, you might think he's about human norm. The fit ones, of course, might have to restrain themselves from constantly winning marathons.
