I had the same problem but got worse in a couple days were everything I drank and ate came back up, because my headache was bringing on such bad nausea. Doctor fave me
zofran and told me to take 1 Tylenol 3 to get rid of the
headache one and for all. He suggested that in the future the instant I feel a slight headache coming on to take regular Tylenol right away. Works better and gets rid of it a the root before it can escalate, because once it dies it can regular Tylenol is no help.
