Yeah I felt that way at first but I honestly don't consider myself a looser at all by going to bed early on the weekends.
I just think about all the super positive things my life like good grades, all the submissions in jiujitsu that week, my girlfriend & her amazing personality and all the sober time I have acquired! I have a feeling all the "cool" people out partying will eventually be asking me about sobriety at some point when they begin to feel empty inside. Me, I know who I am, accepted it and can say I am proud, which was hardly the case a 1.3yr ago.
