Hi,

Thanks for your query.

The grey colored vomiting could be due to the undigested berry pulp.

Sometimes foods containing concentrated carbohydrates or fibers can cause sphincter spasm and prevent food from entering the intestines. This results in vomiting and stomach ache.

Need not worry, the pain and the vomiting will subside without any complications.

Its better to take antiemetics like Metoclopromide after consulting your treating doctor, meanwhile do take a glass of warm water with few drops of lemon juice in it. This will relax the sphincter and allow the food to pass below.

Hope, I answered your query.

Wish you goo health.

Regards,
