Hey Anonymous,
Whatever you do, just make sure you don't touch your bris. That has to be the ultimate red line in the first couple of weeks.
Secondly, you have to ACCEPT that it won't be easy to break free from such an insidious and pleasurable addiction. I remember reading somewhere that when a man tries to stop spilling seed, the thousands of Klipot that that individual created through his sins go crazy and try to do EVERYTHING to stop him escaping. Knowing this can give you something concrete and tangible in your mind to fight against.
Also, I know that when one is mired in this addiction, nothing else seems to give such an intensive shot of pleasure and satisfaction. 'Healthy activities' can often appear a bit boring, goody-goody and smell of hard work. However, the more you persevere, the more these 'boring things' become enjoyable. It's a bit like the Jews who followed God into the desert in order to escape Pharoah - I'm sure you'll reach the promised land in less than 40 years though lol.
Just hang on in there and don't give up cos you can do it!! It's all in the mind.
TC and KUTGW,
