I think I am a bit late to reply but let me tell you one thing. The best solution of all these problems is the EAT. Eat as much as you can, the things that docs have allowed you to eat, eat them as much as possible.
For few days keep your stomach full to the extent possible and after few days call me a liar if you were not feeling better already. InshAllah you will get well soon. :k: best of wishes.
