Why do i feel like vomiting everytime i drink milk? but also experience stomachace after drinking coffee? thank you!

This sounds like you may have an inflammation in the stomach such as a gastritis or perhaps an ulcer. Would recommend seeing a physician for definite evaluation. Sometimes a trial of a medication to reduce stomach acid is needed. Sometimes a scope to look at the esophagus/stomach is needed. Sometimes it may be that certain foods are more sensitive to you. Typically can find a cause for this.
