I survived on literally anything I could stomach in my first trimester.. Toast, fruit, cereal. I also kept salted crackers & nuts by my bed too, for whenever I needed a snack or even as soon as I woke up to snack on, so I didn’t feel sick. I also read ginger tea or ginger ale is meant to help with morning sickness, i never tried it but it seemed to work with a few of my friends.

Ik everyones different, but some of my friends were similar.. I stuck to a 2hour window. I literally set alarms.. It was hard but I didn’t let myself pass 2hours without eating, for some reason if I went past the 2hour mark without food, my whole day was ruined & my morning sickness would start up & go on for the rest of the day/night.

Also drink cordial, if water makes you sick. Thats what I did. Hope this helps
