My wife woke up from a chokingfeeling & threw up twice. few dark blobs were floating in her vomit which is mostly water& her last night doritos snack.

Indigestion: She probably had some delayed gastric emptying after going to bed with somewhat greasy food in her stomach. If this is so, the nausea and vomiting should subside. Absence of abdominal pain is reassuring, but consult her physician if symptoms persist or worsen. Flat room temperature ginger ale and some saltine crackers or broth should be tolerated once vomiting has subsided.
