raw foods: I had a banana at 10 and I had a cucumber and carrot about 20 minutes ago, now I feel like I am going to throw up. What would cause this?|||might be the bitterness of the cucumber on basically an empty stomach. i've had the problem with drinking tea first thing in the morning before i ate anything. tea is bitter and i felt like throwing up. also, might be as someone else says. withdrawal from other foods or the small amount of food so far.|||Uhm. Carb withdrawal? sugar withdrawal? caffeine withdrawal? Any of these. Make sure your blood sugar doesn't get too low.|||raw foods are harder to digest. some people also react to the pollen on the skins of raw food.
