Hey this sounds like what I was going through! It's eased up on me the past two nights thank god (though I am a bit worried why it suddenly disappeared?) I think actually now that I think about it the thing that I changed in the past few days was that I started occasionally eating sugary things, like I bought those Sunsweet Prune "Ones" and ate them like candy whenever I felt a slight bit queasy and they would help within five to ten minutes or so. Then, I started wanting hot chocolate and whenever I'd have that, I'd feel better. Yesterday I even went so far as getting a Twix from the store WITH my hot chocolate lol, and at night I had to run to the store for tp and I picked up a chocolate bar, and whenever I'd wake up hungry in the night, I'd just eat that. I know it's not the healthiest solution, but I think things with high sugar in them really do help stave off the nausea. High sugar things sounded DISGUSTING to me until I actually ate/drank them, and then I was like, "Wait, I want more of that!" I think it'd be more healthy to have GOOD sugars like berries (I saw another poster say something about that) but in the moments that is all I had available.
Also, I keep almonds by my bed because I find they help, and crackers. I also drink a calcium-magnesium supplement because I read that magnesium really helps with morning sickness and believe me, it does! I'll private message you the brand I use because it works like magic, again like the prunes within about five minutes of drinking it, and it doesn't even taste that bad.
