Hi, Welcome to Health care magic forum.
As you describe, you have the change in your life style, life diet habits, etc.
Avoid the calories, fats, oils, junk foods, fleshy fruits like guava, and banana.
Practice, morning walk,
yoga, gardening, and house hold works like cleaning, keeping things in order etc.
Minimize the sleeping time, practice late to bed, and early to rise. Avoid the day time sleep.
You can have any drinks, it makes no difference.
wishing for a quick and complete recovery. Thank you.
