Hi hun, I had this throughout first trimester until 12 weeks, along with severe vomiting and it was awful.
It does - usually - improve, but some tips I found in the meantime were:
Bran flakes. Small bowls, with some sugar & milk. You can get these reinforced with folic acid so if you can't keep tablets down at least you're getting some. I found the clue was to allow myself to throw up first in the morning, then slowly get these down me ASAP...it did help.
Having ginger biscuits or breadsticks next to the bed for during the night & first thing in morning when I forced myself to nibble them. Allowing my tummy to get empty & acidic made the aversions & sickness far worse.
Frozen grapes. If I couldn't stand anything else, I could manage to suck frozen grapes as they didn't really taste of anything.
After every tiny meal I took Windeze. These are amazing for reducing discomfort & bloating which can really put you off food.
Don't try to eat anything you don't fancy but do keep pushing yourself to try. Avoid strong smells, preparing meals etc. my dr said not eating wont harm baby but not drinking will so focus on fluids
& remember it does pass eventually
