Nausea and Vomiting Tips Please

Ladies - what are your tips and tricks for dealing with nausea / vomiting?

I am 7 weeks in, and nausea / vomiting just started last week.

I have been puking 2-3 times a day (once in the morning, at least once in the evening ). Just looking at food / smelling food is making me feel nauseous. Any tips would help! Thank you much!!!!
