Diet is the keyword.

2 weeks before the first dose, need to maintain a healthy diet and drink lots of water.

In my case, I drank green tea for the last 3 months daily and up to 4 times daily. No sugared water except 1-2 times per week. No coffee too. And no bubble tea also.

As for food, I had mostly home-cooked food at home. Only once a week had instant noodles or fast food like McD or BK. No mamak or oily kampung foods.

As for excise, I had none. Only few walks up and down the stairs daily. No going out because no taman in my area and don't want to risk paying any saman.

My only allergy is shelled seafoods like prawn or lobster. I stayed clear from those for almost a year already. If I had those, the skin will be itchy for days.

Lastly, need plenty of sleep and rest. Since my company unable to operate, I mostly slept early till 10am the very next day.

After first dose of AZ, I felt tired and slept for nearly 12 hours. Woke up with a headache. Took 4 tablets of Panadol and all ok.
