hi, i am 24 and have been sick for about 6 years now, i had a period recently where i wasn't sick or gagging, but like you its back and making me feel worse than ever. As you know this is anxiety about the things you are about to do, meeting etc, I get it when ibrush my tongue too and now i tend not to brush so far back, that way i know i cant be making myself gag, have you got a dry mouth for a while before you start? If so then try sipping some room temp flat lemonade first thing, that helped me, also if you have central heating on a timer that comes on before you wake that could be making you feel worse. Sorry this has turned into an essay, just try to remember that you do what you do everyday and that it will be alright!!
