Trying (again) to quit We*d

Since the first moment that I tried smoke weed I really like it but it was something very rare to happen. but soon as I started university it became more and more frequent to a point that it has been over 2 years that I smoke regularly. At one point I think that it could be like a hobbie, that I can mix it with my responsibilities and my daily life. Surprise, I cannot do that, i have the realization that smoking dope it’s Incompatible with my life and the construction of my project of life. Now I had a trouble here at home with my family, I think that it’s time to leave it (in the past i tried to take a detox, and it worked but I failed again). I know that smoking this is an addiction and im hurting myself, Im not going to fool myself anymore. Till this day it has been 3 days completely sober, any advice for the future days or some thoughts about it?
