Im 8 weeks now and can finish my meals with appetite. But once I finish them I feel nauseous.

I don't have bad MS. But I'd still have them. I would feel like my appetite is up and ready to eat, and I can finish a meal. But once Im finished with the meal , I'll feel sick and feel nauseous like my MS would come back. It's so bad that sometimes I would gag at the smell of food when I'm washing the dishes. It's so strange. Anyone experiencing something like this?
