how far is too far?

i'm having a hard time wrapping my pea brain around this one....anyone else out there relate?

the diet's begun. you've been oh soo good. then you discover the bag of oreos in the back of the pantry. you think about it, but dismiss the thought, closing the pantry door. for the first few days, everytime you open that pantry door, those oreos are staring at you, beckoning you. after a bad day at work, you open the pantry to figure out what's for supper, and you see the oreos. "oh i'll just have one quick before supper....it won't hurt," you rationalize.
next thing you know, 5 oreos are gone. you throw your hands up in exhasperation and declare you're diet is officially ruined!!! but it's ok, you'll pick it up again next week. but it doesnt' stop there. you've already had 5 oreos, since you've already fallen off the wagon and won't start again til next week, you might as well off the entire bag!
and so you do, gain a couple of pounds, and feel like crap.

what? you've never blown a diet? good for you (and lemme know your secret, eh? :P) how about this lil scenerio: you're up late one night, doing some "research" online. bored, or perhaps frustrated with lack of progress, you find yourself takin a lil break in a chatroom. now you know which rooms are "bad," so you avoid them. yet the conversations seem rather dull. then someone catches your eye, you exchange a few whimsically intelligent comments. at last, a break from the boredom! sure, you can discuss politics and weather, and the crappy assignment you're working on, but soon, the door is cracked just a lil bit. a few compliments later, you realize you're flirting. but it's harmless, it's just a nice way to pass away the time, you try to justify. soon the compliments turn into sexual innuendos and advances. you may resist once or twice, but eventually give in. oh crap! so much for maintaining purity and integrity! i've fallen this far, i might as well get something out of it......and so the conversation crosses the line into the depths of sexual perversion (well always perverted and extreme in my case, anyhow). you obtain release, but feel like utter crap afterwards.

why do i have this all or nothing mentality?? why is it that when i realize i'm in a compromizing situation, i don't slam on the brakes and run the other way?? why do i always opt for the self destruct mode?? if you're gonna blow it, you might as well blow it big.....where's the friggin logic in that??

is there anyone out there who can relate??
