I too have been suffering from nausea for many months., It will be 12 months in March to be exact ( I'm not trying to scare you or anything, I am just telling you about my situation )
I have had so much bloodwork done and other tests, I also had an upper GI x-ray. I know how you feel about not wanting to eat anymore. I did the same thing for about six months, and then the doc. really got on my case about it and said that if I ate small meals over several periods in the day I would feel better . Feeling better as in the heartburn would not be so bad and I would feel less nauseaus.. which was true.
What I do to get relief from the nausea is I chew gum or eat something with peppermint in it. I find it helps but it's probably not too good for your teeth or stomach to be chewing gum constantly.
I know how frustrating it is to be told there is no soloution, hang in there though.
good luck with accupuncture and I really hope you feel better and find something that helps you.
Don't frown, because you never know who might be falling in love with your smile.
