I understand your feeling.
If you're unable to take more amount of food at a time. If you can only have 2 rotis at a time. Increase the frequency of your meals. For example if your having 2 rotis 3 Times a day then increase to 6 Times a day. So that you will.get enough nutrition and also you will help yourselves in boosting up your appetite. If this is not happening try out different kind of dishes that whiCh is suitable for you and make a list of such kind of dishes and have them.alternatively so that you will not get bored of it.
