Tips on not getting hungry & curbing with nausea

Anyone can share tips on not making my stomach empty? I get hungry easily, like say ard 10am+, 4pm+. I've been eating biscuits for the pass few days to curb the hunger pangs. I feel like i got alot of wind, keep burping & passing out gas. Each time i poo, i will merlion something out. Either water or some food stuff.. #pleasehelp #advicepls #1stimemom #blurlikesotong
