i remember i had nausea and vomited a lot during my first trimester too, i always had sour candy with me, used vicks inhaler and eating small meals/plain biscuits seem to help make it more bearable.
Alternatively, can get nausea meds that r safe for pregnancy from doctor as well though i tried not to take any medication (personal preference)
ok to eat sweet food but just remember moderation is key! ☺️
all the best! this will tide over soon (hopefully)!! 🫶🏻
