Hi..your tirednedd is coz you r not eating properly due to nausea
and whatever little you eat goes in your diarrhoea
...so eat curds and preprobiotics to improve your diarrhea
... bananas will also help...for nausea, eat small freqent meals and walk fir a while after eating...take any ppi with domperidon combination..you will be normal again..
