In my experience there is no quick fix
If you are planning to become sober overnight and demand that, usually it leaves you in the same mess you always were

Are you willing to go the extra mile?
I.e. Will you do whatever it takes to get sober over time, which we take day by day?

It may involve

1] Great Daily calls (perhaps talking there once in a while)
2] Group meetings (only if you need that which many of us do)
3] Writing daily here on the forum (as I try)
4] Getting the phone # of 1 or 2 guys
5] Other tools...

Start with the GPS below and all you gotta do today is decide which route you wanna take

KEEP ON TRUCKING


 

Hi welcome to GYE,

We all struggle with shmiras einayim and impure machshuves. And we all want to be close to Hashem. One simple thing I found out during my recovery is that we tend to use the pleasure of sex and sexual related activities to escape the real world. These "falls" are our drug for something that we don't know how to handle in real life. Try to figure out what feeling is causing you to have these thoughts, and try to figure out how you can deal with the issue in a better way.

Welcome GHOST! 
​I find that the primary tool I have for dealing with inappropriate thoughts specifically is Shmiras Einayim. I don't mean to be cliché, but my experience is that these type of thoughts thrive on mental images which are fueled by what I see in the street. Although unfortunately I've seen plenty of bad stuff, both in the street and online, images do fade and become less vivid overtime. This in turn makes inappropriate thoughts less of a problem. So the better Shmiras Einayim is, the easier Shmiras Machshava will be. 
L'maaseh, this is not my chiddush. Chazal have taught us - first "Ha'Ayin Roeh" and then "HaLev Chomed". 
Hatzlacha! 

But "velo sasuru after your heart" precedes "your eyes", and by me it's reality

I find the blow it up method helpful. 

Once you're clean for a while the thoughts aren't as fresh in your mind and become easier to deal with.

It takes practice to get good at it.

Just don't give up, because it's possible to get there and it's worth it.
