This morning woke up dizzy, seems to have caused vomiting
Various reasons can be there behind morning dizziness and nausea/vomiting
I can understand your concern.
There are many reasons for why you experienced dizziness and nausea or vomiting in the morning.
Abnormal blood pressure and low blood sugar can be excluded as possible causes, given that you refer they were in the normal range. The most common reason for dizziness and nausea in the morning is dehydration, which may be due to a hot environment in the sleeping area, drinking too many caffeinated drinks before bedtime, alcohol consumption etc. So getting enough water during the day and in the evening would help solve this problem.
Also, certain medications that you may be taking regularly can be a cause of nausea and dizziness in the morning, so please talk to your doctor about the possible side effects.
Another reason may be sleep apnea. This is a breathing condition, where the individual breathing disrupts temporarily during the night, which may lower oxygen levels in your brain and as a result, you feel dizzy and possibly nauseated. Those who're with you can verify this. If not, you may discuss this with your doctor for further evaluation.
I hope this helps. Please let me know if you have any further questions.
