I don't think you're a wimp, you're an addict. Addicts can make excuses and rationalize anything. I convinced myself that I was a "light dipper" because a can would last me 3 days. WTF?!! Anyway, my point is that once nic has its grip on you, you can't even trust yourself. Setting a quit date in the future is dangerous because it gives nic more time to think of other excuses to delay your quit. Also, setting the date let's you dip guilt-free...because you're quitting in a few days, right?
I've done all of that crap. I don't know if it was "lying to mysel" or not because I always honestly intended to quit, something (anything, really) would just come up. I don't want that to happen to you.
There is no better time to quit than right f'ing now!!! Throw that shit away, embrace the suck, and go toe to toe with the nic bitch. We are all here to support you...but you gotta quit first. You make the first move and commit to your quit, and we'll be behind you every step of the way. You've made a great decision. Now execute it!!!
