Feeling nausea

I used to feel really uncomfortable, although no vomiting yet.. but as others suggested, small frequent meals really helped.. I eat/snack every 2-3hrs on plain crackers/nuts/bread (unfortunately i realised i have food aversion to meat and any too tasty, even pic or video of these food 🤢).. and I always eat about half or so of a meal at any time as I learnt the hard way if I eat too much at any one time, I'll feel nausea for the next few hours.. and make sure never empty stomach too as that makes the nausea feeling worse..
