In addition to what Dr Weyinmi said, u can take more of fluid diet e.g Pap, oatmeal, custard and fresh fruit juice (home made) like water melon, pineapple etc.. And take little at a time, take ur time, Start taking folic acid if u haven't started and take plenty of water too, I know it's not easy but take little at a time, u can flavour it with one quarter of a lemon to make it more palatable but if all these still doesn't work...Go to d hospital pls!
