Welcome Lj! This is the best decision you ever made, and you are in the BEST place for support, and help.
What you are experiencing is very common among new Quitters. So are sore throats, bleeding gums, and a whole bunch of other shit. You've poisoned yourself for how ever many years, and now 7 days later (congrats, btw), your body is throwing a temper tantrum.
Get some seeds. Gum. Life Savers. Fake dip (no nicotine). Mints. Toothpics. What ever you can get your hands on to help with the oral fixation.
The nicotine is out of your system, now it's a mind game.
Welcome aboard,
-Nolaq
