Hi Rebecca and welcome!
I'm glad you know you need to stop drinking. Blackouts are terribly scary. I had them during the last months of my drinking and I have never forgotten them. I think having a plan for how to stop drinking is the best way to begin. If you look around here you will see lots of different ways that people recover. My suggestion for the early days is to shake up your routine. Change your weekend plans completely to help get through the days. You can do this!
