Wow, I am sorry to hear of this condition. It sounds very terrifying. I usually feel nausea mostly when I consume dairy products for some reason. Not all dairy does it to me, but some of them do. I have no idea why this is happening, but if you are on medication, unfortunately they come with effects that cause some very strange happenings in the body.
You can try this out first thing in the morning to help curb your nausea: Cut off about 1 inch of raw ginger root and bite into it. Drink down the "juices" that form in your mouth of biting it with room temperature water. Not a lot, just a little at a time to get it down. In addition, you can make a tea out of some of the ginger root as well. Just cut off a "block" of it and put it into boiling water for about 5-10 minutes. Drink a glass of it. Wait at least 10 minutes after consuming this ginger root concoction to eat some fresh fruit. Any fresh fruit of your liking.
So to recap, chew on a small piece of raw ginger root and drink a glass of homemade ginger root tea first thing in the morning. Then wait 10 minutes or more to eat some form of fresh fruit.
This should help you out.
