Ramadan question....

This is my first Ramadan. I need some advice please sisters.....

I'm finding I can't manage to eat much during the nights and am drinking about 5 pints of water. I knew thirst was going to be my biggest issue but my stomach hurts when I eat and I'm not eating enough. I just feel massively bloated! Its approx 18 hours of fasting where I live. Does anyone have any suggestions to help with the bloat?? I'm not hungry at all and feel like I'm eating for the sake of it.

Thank you in advance xxx hugs x
