the only thing that worked for me was to obey the body..
It was bad.. really really bad at first..
I just learned that I could not be around anything that was being
cooked.. any smell of food would make me puke..
futthermore I just could not eat anything hot that would release
any smell
so I only ate cold things especially sandwiches worked okay
small and always small at the time
I figured out that my body just decided what to keep down and what not
as it knew better then me I figured that many things were not "apprecaited"
by the system and identified as "not acceptable" and had been returned to
the feeder

therefore I was just not eating untill I really felt hungry and then again
only cold sandwiches.. very simple.. slice of bread, one slice of letuce
and one slice of organic cooked ham and not even top slice of bread
just open faced sandwich european style. on square bread.. prefferebly
multigrain organic.
watermelon was sitting well as food, drink and all that.. it is loaded with
iron and other vitamins and it cleans the toxins from the body so it was
accepted so to speak..
other then that I could not cook.. I had my mom over some time and I had to
sit upstairs with doors taped around! window wide open.. literarly as she was cooking for the family and I could only go downstairs once all the smell was gone.
no restaurant going.. I would not stand any smell.
look of the food would do this sometimes too when I was not hungry
or just ate..
other than that I do belive that this is some sort of self-defense system
and it knows what it is doing. I think that some substances in food
might be not needed for the baby and harmful so it just rejects them.
I think that going to the prehistoric time and thinking what the human race used to eat for the last million yeasr as opposed to the last 7000 when we actually have a crops.. eat milk, cheese and all this stuff might be an answer..
first humans and for that matter most humans through the history of 1 mill years with the exception of those last even ... 10 000 years (which is a blink)
used to eat: meat, meat... meat.. as they were mostly hunters
and then they would find some berries.. and some more berries and
such
there was NO farming, NO veggies.. NO Dairy consumption etc..
so most likley we are designed that way
You might want to try and see what happen if you will focus on
meat and berries

.. technically all one needs as meat has all carbs
and berries all vitamins and minerals..
I think that body is having problem with our modern (the last 2000 years

diet.. as we use and abuse:
eggs.. nuts.. grains.. and those are highly packed in genetic material for new beings.. plants and animals and they might conflict with new baby growing inside..
then add to it cheese.. milk.. all this stuff is packed with hormons
add the crabs, shelfish.. that stuff is just super strong and alergycausing substance even in healthy people.. stay careful with it best away..
It is of course just my theory and I am not a doctor but this is interesting non the less..
Otherwise if you are not skinny and drink plenty of water when and however possible you should be fine as this will pass and technically your body has
enough fat tissue to support the baby even if you will eat minimum..
as long as you eat somethign and drink something regularly.. as in.. whenever possible..
It is a pity that you can't stay at home and rest more as your body must be exhosted.. aside from the fact of not being able to eat..
I quit my job as I was too weak to work and I choose the baby well being
and mine over work as I just could not manage.. it was that bad.. really bad..
but my bed rest and taking it easy helped to sail safely.
