I really want to quit alcohol bt dont want to be in a rehab or on bed, is there a way i can try myself to quit with getting hampered my daily routine( job). I also want tht my damily shudnt knw abt it. I feel guilt vry nxt mrng whenevr i drink bt feel heavy craving aftr office in eveng. Hv tried in past as well bt one odd occasion, i start again n it cntinues whthr i enjoy it or not. Whn i dont drink feel like crawling on body, imaginary things in frnt of my eyes, smtimes feel like smone talking behind my bed bt nothing is there.
