Am i psychicallly addicted?

On fridays and saturdays i like to eat about 10 Acetaminophen: Hydrocodone Tablets 500 mg, 5mg (vicodin) these pills are def a narcotic and 10 of them is nothing short of a BAG OF DOPE!! i also drink mabye 10 drinks on friday and 10 drinks on saturday with them at the club and when its time to go to sleep ill take two .5mg xanax its been a routine for me for the last 4 months or so and i enjoy it so much that i dont plan on stopping any time soon. The funny thing is that mon thru fri i can work and excercise normally and sleep semi normally. I dont really get psychical withdrawls like people talk about. i may get a little anxious but thats about it. I eat normal and joke around normal and can maintain my daily scedule without any drugs or alcohol at all. What will happen f i keep up this routine??
