Two weeks ago I was in the same boat. Severe migraine and vomiting tons of bright yellow bile. I also suffer from frequent migraines leading to vomiting....long history of this.
I asked
Andreas Moritz (another forum on this site). He said that my liver and bile ducts are severely congested, therefore regurgitating bile back into the stomach. I was not digesting food properly and therefore vomiting.
What I did...took care of myself, got over the episode, ate 'lightly' and prepared for a liver flush. YOur husband will probably need to do a series of flushes (spaced at least 2 to 3 weeks apart) until he gets the bile ducts cleared and releases stones from the liver.
I would strongly recommend
Andreas Moritz 's liver cleanse protocol. You can purchase his books online from (I think) 1stbooks.com
I know, your husband is feeling awful. I can relate. Just get going on some
Liver Flushes and he will soon feel better and digest better.
Take good care.
