Well done on not drinking since Saturday. You know how much you loved being sober for those 3 years. You can get it all back, despite what your head may be telling you at the moment. Were you in AA whilst sober? Or would you consider going to meetings now, to help you regain long term sobriety? You could definitely do a lot worse. AA certainly helped me.
It's a godsend that you don't crave cocaine when you are not drinking, so alcohol is your primary concern. Post as much as you can on here, and consider getting help in your local area. It can be very tough at the beginning, but as you know, it WILL get better just by putting in some actions.
Sorry to have not replied sooner, but only just saw your post. Better late than never! Have a sober day today and tell yourself often that you can do this.
