Why do i throw up every time i get a headache? i usually get them in the morning when i wake up. they are usually on one side of my head and i have pain in my neck.

Migraine: What you describe fits with symptoms of migraine. See this site for information on this subject and consult your doctor as there are effective treatments available. http://www.ncbi.nlm.nih.gov/pubmedhealth/pmh0001728/.

Migranes?: Vomiting can occur when you have migraine headaches. I recommend seeing your primary care doctor to get a diagnosis.

Migraines: It could all very well be part of migraines. Consult a neurologist.

I too would say this is due to migraine, and apparently, this is becoming a consistent pattern which needs to be addressed. A preventative medication would control this, and neurologists can provide interventions which will result in cessation of your episodes.
