Hi there , yes i just finish my 1st cycle of chemotherapy (each cycle 2 time )  last friday and  my 2nd cycle will start on this coming friday. Luckily the side of chemo doesn't go too harsh on me . what i had experience which is a mild fatigue , loss appetite ,constipation(2nd and 3rd day after chemo) , feel bitterness in my mouth (It may last 3 to 5 day). However, i still able to go  for jogging after chemo (it is not advisable if u feel extreme tired and weak ).
it is sad to heard ur dad also been diagnosed with  NPC , but dont worry , with advancement of medical technology this disease is highly curable especially during early stage. what i can advise is listen to what doctor said  ,always stay positive (i know it maybe hard  but family support is very important  (For my mum always be my side  ) , eat healthy (alot veges and fruit avoid toxic food like prawn and etc  ) and exercise more frequently  (i went for jog 5km everyday before i start my chemo ) . i believe exercise  will help in boosting metabolism as after chemo our body can produce new cell more quickly and therefore side effect will be mild.
so after 2nd cycle , i will proceed to radiotherapy. I will update again once my radio start. Stay strong !!!!
