I can go full 30 minutes without swallowing most of the time but my problem is that whenever i start to get bodily sensations like feeling weightless or heavier or my body detatching from my physical body i always right at that moment i get the urge to swallow even if i dont have any saliva build up.I try to hold myself from swallosing because if i do that at that point everything stops.The feelings stop and i have to restart and it is frustrating.The thing is that i try to hold myself from swallowing and after a point it happens by itself like my muscles in my mouth contract themselves and make me swallow.Also sometimes i get tachycardia where my heart beats like crazy like i am runnin g a marathon which after sometime also make the bodily sensations to stop.Can anybody help with my issues?
