Finally settle down with the 3rd booster today afternoon.
Dehydration start this morning and the normal side effect, minor nausea, gastric , bone pain and so on continue .
But, overall is very much better than expectation .
Drink a lot of water today to counter dehydration and since yesterday start with small input per meal to counter the hiccup and gassy stomach. So far, works very well with it .
The 3 days medication with Dexamethasone completed yesterday, so, today have to start dealing with side effect without Dexamethasone.

How does this drug work?
Dexamethasone is a type of steroid drug known as a glucocorticosteroid. It is a man-made version of a natural hormone produced by the adrenal glands. Glucocorticosteroids have a wide range of actions on many parts of the body. The ways in which they cause these many different effects aren't exactly clear.

The main effects of dexamethasone and steroids like it seem to be due to their anti-inflammatory properties and their ability to alter immune system responses. For example, dexamethasone helps prevent white blood cells from traveling to areas of the body where they might add to swelling problems (such as around tumors). It also seems to help with the treatment of certain blood cancers (such as leukemias) by causing some cancerous white blood cells to commit suicide.

The reasons for some of its other actions, such as increasing appetite and reducing nausea, aren't as clear.

Anyway, for until now, everything is well and with Lord's blessing, I will cope well in coming days.

Good nite ... :)
