I got awful headaches when I stopped drinking coke and coffee, maybe it's a similar thing.

What have you eaten in the last couple of days? Have you been drinking enough liquids? I would try saltines and ginger ale, or failing that, 2 oz of Coke every 15 minutes -- that should help the nausea. When your stomach feels better, make sure you get plenty of liquids and you've eaten some saltines or something, and then take some pain medication.

I wouldn't think just forgoing meat for one day could make you this sick, or omnivores would get sick all the time. It sounds to me like you're coming down with something, possibly compounded by not drinking enough water.

Vegan with a doctor for a mom.

After making a major change to your diet it's normal to feel nausea and headaches for a week or two. Are you eating healthy, getting enough water, vitamins and minerals and everything? If so then wait for it to pass, unless it becomes debilitating or you think you have caught something not related to how you are eating or if it lasts too long, in which case you should definitely see a doctor.

Why the heck are you eating dairy? Are you a cow? What rational thinking, sensible humans thinks taking milk from a cow that a completely different species be considered a natural thing? humans were never made to drink cow milk. Do you have bestiality tendencies or something?

Anyway, you maybe lactose intolerant, which completely normal. The fermentation of lactose leads to the typical symptoms associated with lactose intolerance. The classical symptoms are abdominal bloating, cramping pain and flatulence. Diarrhoea is a common symptom as well but varies from individual to others, depending on how much lactose they can tolerate and how much lactose they have consumed. Other characteristic symptoms include nausea, gaseousness, rumbling and in some cases, especially in children, vomiting. I believe that the nausea and vomiting are caused by the escaped gas from the fermentation back into the small intestines and stomach.

Symptoms associated with lactose intolerance may be mild or severe depending on the degree of lactase deficiency and the amount of lactose sugar consumed.

Symptoms:

* Abdominal pain - cramps, often localised to the per-umbilical area or lower quadrant
* Bloating - caused by the formation of gases that expand in the warm conditions of the digestive system
* Flatulence - caused by the gases produced by the bacteria. H2S is the gas associated with the odour
* Borborygmi - may be audible to the patient and on physical examination
* Diarrhoea - stools are usually bulky, frothy and watery
* Vomiting - particularly adolescents
* Nausea - may be present, probably due to acidity and gases escaping backwards
* Weight loss - if kept unattended
* Malnutrition - especially in babies

Your first week of being a vegetarian or vegan will be pretty yucky. Let your body go through the withdrawl. Don't take pain meds. Iron is found in spinach and other green, leafy veggies. B 12 is found in seaweed, sold in health food stores.

I also stopped eating sugar as well.

It's very normal to detox, despite what others are saying, if you've eaten a lot of crap, drank pop, coffee, etc and are now doing the healthy diet.

I would lay down and take it easy, and see how you feel tomorrow. You might just be getting plain sick. I don't see how you could start immediately feeling nauseous after one day of being vegetarian. Just remember to eat healthy :)

It's probably just coincidence or something you ate that wasn't prepared properly. Have yourself some tea and see what it does after a while.

Not eating meat does not cause nausea or headaches.
The only time not eating meat would make you sick if it is literally THE only thing you eat. Go see a doctor if you're sick :)

It's probably just withdrawals. Make sure to get iron, because it will make you feel nauseous if you don't.

Not a surprise if you went from eating meat every day to being a vegetarian. It will pass...

your having withdraws

You're probably just getting used to it. Try to get more iron.
