Morning sickness ... Advice!

Andrea
This is my first pregnancy. I am 6w6d and the morning sickness has officially kicked in. I know it's very normal but I am a teacher and have to be around young children all day. I am finding my energy levels and nausea are making my days really hard to get through. 
​I am not sure if anyone has any advice for me (if you are going through it or have gone through it). Food to eat that helps? Anything would be great. I know everyone's body and pregnancy are different but I will try anything ! Thank you!!
