Hello ? I wrote about appetite before, can't eat normally, already started feeling a little nauseous in the morning but don't throw up, there are medications that need to be taken after eating, and I can't even swallow a piece of bread ? Can yogurt be eaten on an empty stomach? I think I can eat 2 tablespoons. ??‍♀️
