Why am i nauseous in the mornings?

I would go to the doctors to check it out. 2 hours is a long time to be feeling so rough every day. It may be blood sugar problems, I find eating a bowl of porridge before sleep or something else a bit stodgy helps. Or it could be stress, especially if you are getting the dizzy thing. Make some time each day for proper relaxation, use a relaxation cd or something to make sure you know how.
