I have been vomiting since past 2 weeks

I have been vomiting since past two weeks when I moved into my new room and got fever.
I omitted all unhealthy food and drink plenty of fluids but they seems not help.
I tried Chi-Kit Teck Aun pills and it's ok for 2 days only. I ask for help to one of my ward specialist and he prescribed me Cap Omeprazole 20mg OD and Tab Domperidone 10mg TDS. They really works, until I forgot to bring those to Rantau Panjang and not taking them for 3 days, then the vomiting and diarrhea begins. Now I resume back the medication since I think most probably I got Gastritis, (perhaps not!)
Hope I get well soon!
