I've had morning sickness all day for 2 weeks and tonight it disappeared?

I'm about 6 or 7 weeks, not entirely sure yet since I don't know the date of conception. I have had pretty moderate morning sickness alllll day for almost 2 weeks, and I had it today but after I ate around 1 PM it went away. Even when I became hungry again I didn't get nauseated. I even just now ate a crap load of jalapeno potato chips and twizzlers and I am very full which usually makes me sick but I still don't feel sick!!! My boobs still hurt. I'm kind of freaking out thinking maybe its a bad thing I am not sick. Has this happened to anyone else? Does the sickness come and go? This is the first time its let up in 2 weeks. I did take a vitamin called Morning Ease from the organic food store but I took them yesterday too and didn't notice a big difference. :( Help.
