Cravings

So I never had been a smoker. I tried a cigarette once and HATED IT! Before I even knew I was pregnant I craved a cigarette. I decided against my better judgement to go ahead and smoke just one while my boss was outside. The moment I found out I was pregnant I have stopped it was only one slim cigarette (found out at 5weeks). But my question is: does anyone else have just off the walls cravings they never cared about before?!
