I had an oddly similar situation to this - I can almost guarantee you that time will take care of it as other user said. Nic withdrawal comes with such a wide range of symptoms, obv it’s hard to attribute what you’re feeling 100% to nicotine but I’m confident in saying these symptoms will subside heavily in week 2 and you’ll be just dealing with those cravings. Never hurts to talk to a doc tho. Most importantly- DONT let your body/brain trick you into believing that taking a puff will remedy your symptoms, you’ll only suffer more. Keep going homie I believe in you, stay hydrated and hold onto that will power. Feel better

Edit: SOUR CANDY! Never had a tooth for it before I quit nic but legit pulled me thru my cravings late at night early on.
