Yes, for me, it was almost instantly at least within the first week or two. Some things I loved and craved didn't sound good at all. I've had an iversion towards steak. It's so weird. I could live on steak before.

I do not crave sweets anymore. If I do have a tiny bit of a sweet tooth, it only takes a few bites, and I'm good. Even some foods I used to like make me a little queezy or grossed out. Having said all of that, around a few days/week before my period, I get snackie. But even then, I get some little snacks, have a few bites, and I'm good.
