HolyDooly,
In the first 4-5 months I gained ~ 20 lbs. I rolled with my quit, and ate whatever I wanted, and continued to exercise every day. In four days, I will be 9 months quit. I have returned to my pre-quit weight! Additionally, my body may weigh the same but it looks more feminine to me. I love it! It's less like a skeleton and more muscular and soft. Good stuff.
About "locking yourself away." Why not? Maybe you need to hide away for a bit - accept yourself for your abnormal reactions and behavior. Even @ 9 months I sometimes act like a petulant child. I'm dealing with emotions I smoked away for over 15 years - - OF COURSE I'm a little nuts. My rule is: as long as I don't seriously injure myself or another, I will do whatever it takes.
Sometimes I'll encounter a situation which floods my system with adrenaline (it feels like I'm mainlining a serious chemical into my veins). This is only my fight-or-flight response and it's working stronger than ever!!!! I'm not accustomed to it. The cigarettes/nicotine dulled that sensation. I've gotten into a bit of trouble for it, but so what? Neither I, nor anyone else, has been seriously injured!!! And I'm currently working on emotion regulation through meditation/prayer.
This is not easy. It's SIMPLE. It's so simple - never take another puff. But easy? Heck no. That's why we're all here to get you through this unbelievable challenge.
2 months is remarkable and impressive. March on.
