Hi Mike,
Not sure which time zone you are in, but it is probably still morning, or early afternoon. You can pour out the rest of the alcohol and reset and start over. Your post earlier was so positive, and you were feeling really good about being sober, think about that as you pour out the alcohol.
Also, you mentioned you just returned from your parents. I am not sure what supports you had in place there, but they seemed to be working. Think about what was there, and replicate them at your house.
You still have plenty of time to stop drinking, sober up, and enjoy the rest of the weekend.
