Sensitive gag reflexes


I am 15 weeks and my gag reflexes are SO strong. I was nauseous all day up until a week or so ago and now I don’t quite feel that but still feel like I’m on the verge of throwing up all the time! Some mornings I do throw up because of it. I gag every morning. I’m a teacher and even sometimes when I’m in the middle of talking it gets to me. I make sure to always keep water by me because that seems to help. Has anyone else had this problem and found something that helps??
