7w 3d morning sickness sucks!

I am 7 weeks and 3 days and this week has been the worst, since I found out I was pregnant (5 weeks) I've been super nauseous but this week I've thrown up pretty much every morning and just feel so yuck all day long. 
I'm going overseas on a holiday with my partners family in a week and a half so I'm really hoping my sickness goes away asap as I know everybody will catch on pretty quickly. 
Please tell me there's a light at the end of the tunnel.
