Typhoid without fever all time is Nrml?

Hello sir, On 26th I was diagnosed with typhoid where typhi O&H 1:40 1:80, AH & BH were not available, monocytes 1% (no fever at all). After 10 days of treatment I was feeling well. But gases were there. I was given some antibiotics, pro and pre biotics and b complex with minerals, I don't remember their names. After 5 days of completion of treatment, I suddenly got same symptoms but were higher than earlier, this time test found both typhi O and H aggulation present, Typhi AH and BH were absent monocytes 0%. Now its been 6 days I have much recovered still I have weakness and random stomach upset. I am given oratril 500, Bplex and vomihalt if I get nausea. Today I felt nausea after lunch. In lunch I ate 2 chapati and some rice. Taken chapati after long time. But within 30 minutes of food I felt nausea and the got vomit. Some pieces of chapati and rice both were there. Since then I am feeling well. Is this condition normal or how can  I prevent vomit. and how to recover further safely.
