Welcome Dippy. You can make the decision to change today, right now... a change for the better for you and your kids.
You have 4 months drink free, so you know how to do this. My wast line took a toll when i was drinking heavily too, so did my red face, puffy eyes, and all-around tired looking body.
That all changed when I started to string together some sober time. I've made the decision to change for good. I'm only 24 days in but we all start at day 1. I've lost weight, no longer have a bright red complexion and look generally healthier... As you know the easy way out is to pick up the drink again tonight, and again tomorrow, etc. But in doing so, you will never be who you are capable of being.
Make the decision today and stick to it; you will feel better tomorrow and as each day passes.
Best of luck!
