Hey Jules,
I know exactly what you are saying!! Its so hard! I haven't actually spewed once, but I've been super hungover for weeks and weeks. And you can't tell anyone about it! Makes life tricky!
In the end I gave up and told my boss. His wife is about 3 weeks ahead of me, and she has had really bad problems.
I explained that I wasn't able to eat in the morning, so by 10am, I really had to go out and get whatever it was I felt like I needed to eat! And I said that sometimes I would need to go home early, but I would make up the time when I was feeling good.
To be honest - my work is a bit of a joke now. I feel like I have been written off, which is pretty hard in a professional role, but I say such is life! My family is much more important to me than people at work. So if they want to keep paying me the full amount, and relieve me of my responsibilities - so be it! Their problem!
The biggest thing is the distraction that this wonderful thing is growing inside your belly, and how can you possibly concentrate on anything else!! Hugs, and enjoy the roller coaster ride!
