Been suffering for years now, seems the only CURE is lowering your anxiety, all my life was been finding loop holes to avoid potential stressful situations, my advice is get help early before it becomes a nightmare and ruins your entire life, medication would of helped early on and potentially stop it, now that I am a adult, medication is only means to coop with it better....
My story...
From what information I've gathered, It seems specific memories, places, smells can cause you to remember things, this is true in my case, when I first had my swallowing habit, I ONLY DID IT IN ONE CLASS IN FIRST PERIOD IN FRESHMEN YEAR, BEFORE LONG IS SPREAD TO ALL MY CLASSES(the other classes I did it but it was not as bad as first period), DURING THE SUMMER IT GOT A LOT BETTER, THEN I STARTED SCHOOL AGAIN, EVERYTHING WAS FINE FOR THE FIRST FEW MONTHS, THEN IT GRADUALLY STARTED GETTING WORSE, AND WORSE, AND WORSE, AND AFTER 6 MONTHS IT TURNED INTO A MAD HOUSE OF THINKING OF SWALLOWING EVERY SECOND. during this time in school I always had a bad time sleeping, it was awful, I did learn however to hold my spit in forcing me to become mute, I told everyone I had lockjaw anyways. I had to drop out of high school sophmore year and finish online, but if I'd of only dropped out of school sooner I would of been able prevent this 24/7 manual swallowing.
THE CURE
People, places, smells, causes memories to trigger, avoid all stressful places that cause you to swallow, avoid all people that remind you to swallow, if you are in school or something try to get home-schooled
