Non stop nausea??

Hey all, I am 5 weeks 5 days along and I feel like I could throw up at any time. All day long. The thought of food makes me want to throw up. The smell of food makes me want to throw up. The taste of food makes me want to throw up. I've only actually thrown up this morning before eating anything. But I for sure held it in after taking small bites of food throughout the day. Anyone else experience this so early? How long did it last for you? What did you do to make it better??
