Hey Steffie, It was 30 years of heavy drinking for me too but I stopped in March last year. My life has never been better, my health is great and I even look way better. I'm doing an online course this year, cycling, walking, working full time, running a home, looking after my elderly mother and it's (relatively) easy these days. It can be the same for you.
You adopt the philosophy of not drinking for one day at a time and your whole life changes. 24 hours is all you need to think about today.
