sorry you're having a tough time SK. I relapsed after six years sober & stayed out for another eight years, so don't do what I did!
I'm not an AA person, so I'm not going to comment on you're sponsor's advice, but I hope you can get whatever help you need to get sober - it doesn't get any easier the longer you stay out.
If you're physically dependent, I hope you can get help with detox rather than having to taper yourself off, as it's safer & a lot less unpleasant!
hang in there & do whatever you need to to stop drinking
