If it were me and I couldn't afford to properly detox, I would have tapered off over the course of a week or two,, but most people find it hard to do that. But seriously, you can die from suddenly going cold turkey. Please be careful.
I just read a couple of your earlier posts and saw you have tried AA. I hope you will consider it again. For those who drink heavily and find it hard to get and stay sober, face to face AA support can be a miracle. I have witnessed several make it into longer sobriety that way. If you gave your local AA chapter a call someone will come and meet you and provide support.
