Afonso,
I don't know man.. Your plan to replace one addiction with another might not work out for you. Pickup can end up destroying your life just like drugs and alcohol if you approach it like you are about to do; replacing one addiction with another. May I suggest looking instead on getting yourself out of the need for addictions, looking to destroy the root cause in your life that drives you to different addictions. Also, there's probably a good reason why Tynan himself has given up pickup, and he wasn't even an addict. Whatever you do, good luck!
