I woke up coughing and vomiting, the color was a brownish thickmilky like and tasted of bile, but did not burn my throat. hard time breathing, thou?

Reflux: It could be from acid reflex from you stomach content or bile, it should improve. If not have it checked.

Bilious vomiting: Gastrointestinal upset when you have not eaten for a while will result in vomit that tastes of bile. That is NOT a diagnosis of something seriously abnormal and obstructive, would try to drink clear liquids until feeling better
