That nausea doesn't sound too good, Seliah! But it does sound like me of a morning. Can't eat for a few hours after rising but can then chow down like a rabid dog
Yeah. I cannot put anything but liquids down my throat for the first two hours after I get up. The only exception to this is if I wake up with my blood sugar levels in the basement, then I have to eat no matter how icky it will make me feel.
I don't eat a lot in a sitting, though. Breakfast is usually a handful of berries and maybe an egg, if my stomach will tolerate the egg that morning. Usually I eat those with a glass of water and my coffee. Yes, I drink both in the morning.
I then generally just "graze" the rest of the day; I eat small bits of fruits and veggies here and there. Usually about once every three hours or so, I'll nibble on something small. I have a lot of difficulty with "main meals" as the amount of food just tends to be too much for my stomach, and if I eat just a little bit too much I end up nauseous.
Meats or anything that is "heavy" will cause the nausea too. I think it's because my stomach is so used to eating basically an outdoor scavenging diet. I can handle game meats okay - depending on how I cook them - but things like sausages or pork; chicken... they make me sick to my stomach quickly. Eggs, sometimes just smelling them cook is enough to warn me that I'd better not try to eat them that day. LOL
Our bodies do get used to what we feed them. If you take a long-term vegetarian and feed them meat, it makes them sick. I do eat meats, but generally only in very small amounts and only once in a day. The rest of the time I live off things like nuts, seeds, berries, fruits and veggies. All of which are pretty "light" as foods go. I find a lot of the "sweet treats" and pastries, cakes, etc... as much as I love the flavor, they are too sweet for me or end up being too heavy in the stomach. I am the type of person who can pluck a few chives out of th garden, or a couple of mulberries off the tree, and they will fill me up for the next two or three hours.
I have a doctor who likes to tell me I'm an evolutionary throwback, and that he never knows what the heck to do with me half the time.
