I can understand your concern.
What your MBBS Friend suggested, you can continue those for some more days.
Avoid oily and spicy foods.
Drink plenty of fluids. Tender coconut will also be helpful.
After you recover also,
Take tab. Neurobion forte once a day after food for 10 days.
Have lots of greens and fruits.
