Listen it's natural, and sadly it's expected. I call it "withdrawal".
When I fist started, I would be plagued by vivid immages of the most graphic scenes! My YH would use my immagination to play-out the most graphic of videos.... using nothing more than my immagination. I was totaly unable to vlear my mind! The only tool I had, was a peice from the sefer Shmiras Halashon. Here is the original post:
[quote]So I has A very hard start...serious withdrawal syndromes...emotionally agonizing torture!!! I would grab the steering wheel as hard as I can, and just fight the urge...until I began enjoying to fight it.....then I welcomed a strong urge, because it make me feel powerful....I am mentally powerful!
Then 2 days later the yetzer hara gave up with the head-on approach, and enticed me so slyly I barely managed to realize that I was thinking inappropriate thoughts. My new struggle was to realize it......Then 4 days later, and I'm keeping myself very busy al day....it stops. wow it was great. No Yetzer hara. Tisha Beav came and went without me even realizing it till a few days later.
i still have a hard time identifying a thought creeping in, but as soon as I do, that's the end of it.
I think that part of this success is that I used to get a lot of enjoyment out of thinning these thoughts, and no enjoyment fighting it, just the stress and struggle to do so. But now that I can proudly tell me Rebbe about my achievements, and post it on these boards, I get more enjoyments fighting them, it's fun, and exiting.
What got me through the last 2 weeks is a perek from the sefer smirat halashon. The chofetz Chaim tells us that after 120 they will give us a sefer torah and say "READ" and when we get to all the placed in the torah where we transgressed, we won't be able to read it. How can a thief possibly read 'thou shall not steel..' he'll be overcome wit such a pachad and aima...he'll be sentencing himself to gehanom by reading it...because He didn't fulfill it. One can transplant this to any mitzvah. I talked to myself (car-rides are great for that) and verbally played out the entire scenario....'and they're going to give you a sefer torah and make you read "Velo Sasuru....avcharei lav'vachem...ve'acharei eineichem....asher atem ZONIM achareihem!!!" .
Eventually this became my rally call whenever I needed it. I would just scream it once (in the car again) and all thoughts of looking twice would vanish (sometimes I need to repeat it a second time).
The sefer cheshbon Hanefesh actually advises (as part of it's amazing system) that one write an essay on the middah they want to work on, then summarize that into one pasuk/sentence, then summarize that one powerful sentence into a made-up gibberish word and whenever that person need to conquer that midah he should say his gibberish codeword [quote]
