Struggling to eat

Hi ladies is anyone else struggling to eat? I’m 5 weeks 2 days at the moment. I don’t have any appetite because I feel nauseas and when I do eat it comes back up. I work 15 hour days and am finding it really hard! Currently surviving on Cookies however I know this isn’t good. What did you do to boost your energy? When did you start feeling better? I travel round all day to my clients (I run my own mobile beauty company) and it’s becoming hard to hide my nausea and sickness. Thanks x
