I can totally relate. I have lived an almost identical cycle for the past 3 years. I'm only 9 days in, but after my first entire weekend of not drinking, I can say I'm feeling like a better person and wife already. I too, had no appetite while drinking and lost a lot of weight but it's not the right way to do it and my health may be suffering as a consequence. (we'll see after I visit the Dr in 2 weeks).
Good for you for posting and taking the step. I have had immense support in a short time here - and you will have it too!!! Glad you are here!
