I decided to give up my nicotine pouches and nailbiting for 2 weeks after learning they are a "level 1" dopomine hit, and i need to rid myself of them in order to reset my dopamine baseline (social media, other impulsive behaviors are level one....level 3s are training for something, executing an output for you business, etc).
I was able to stop nail biting a while back through this method I wrote down. So in summary, I am literally wearing my bottom retainer every where I go and wearing "finger condoms" when I take it out to eat. Instead of judging myself for how "bad" the habit is, I am just dropping the story "I can't, its too hard" and put up PHYSICAL blocks. Try it out! Posting in wins because its 4 pm and last time I bit my nails was yesterday AND I through my nicotine pouches in the trash. I may look ridiculous for 2-3 weeks wearing finger condoms, but then I won't bite my nails anymore AND will continue to reset my dopamine baseline. Join me!
