Craving Veggies?

Does anyone else crave veggies like crazy? Sometimes I wake up and I immediately think "I could go for a big plate of roasted asparagus" or "I would kill for a salad right now". It doesn't really make that much sense to me, it's not like I have seen it in a commercial or magazine since I am sleeping immediately beforehand. It's not even a passing thought...it will stick with me through the entire day. I was prepared to go through withdrawal when I left for school and switched over to mostly processed foods, but it's been over 3 months and the frequency is increasing!
