Must I continue to make up for the days when vomiting overcame me, knowing that the vomiting recurred on the day of making up itself, and I have read a fatwa indicating that I am not obligated to make up for them?

Fasting is valid for one who is overcome by vomit and is not invalidated by it. However, whoever intentionally induces vomiting must make up the fast.

As for one who begins fasting thinking it is obligatory, then it becomes clear that it is not, he has the choice between completing the fast or breaking it, and completing it is better. This completion would be with the intention of a voluntary fast. The statement of Zufar regarding the necessity of completion is also the view of the Malikis.

As for the fluid coming out of the stomach into the esophagus or mouth (regurgitation), it has a specific ruling.
