I had all day morning sickness for 9 months.

It was awful. What I found to help was eating super cold watermelon first thing in the morning (don't ask me why). My husband would bring it to me when I was still in bed. I think something about the sweetness and the liquid content really helped. (But try finding watermelon in the middle of winter!) Super cold canned pears also helped.
I also wore those SeaBand things on my wrists (they are for motion sickness). I don't know if they really helped but psychologically they did!
After the first couple of weeks I wasn't actually sick, but had the nauseous feeling all day. I could only work 1/2 days per my doctor because I felt so bad. That was all I could manage. I think I went on some kind of medical disability (can't remember exactly--12 years ago).
I think you have to keep experimenting and see what makes you feel the best.
Good luck! And Congratulations!!
