QUESTION RE- PHYSICAL WITHDRAWL

Hi folks. I've read that the physical withdrawl symptoms last a few weeks. Problem is I think I'm still having this after 2 months. I keep feeling a pulling sensation in the back of my throat and a tightness like sensation in my mouth,quit smoking, which is temporarily sated if I pop a sucking candy. Also a tightness in my chest front/back. The physical feeling truly stinks and I keep wondering what the heck is going on. I didn't having any of this prior to quitting,quit smoking now, am starting to think I'm some kind of a nut or something. Did/does anyone else go through this? Sometimes I feel like a cat chasing my tail, not a good feeling.
