Definitely doable Loulou; and you will actually enjoy the Holidays so much more. Last year was my first Christmas sober in 21 years. The great thing, I didn't have to play like I had the flu on Christmas morning due to drinking way too much Christmas Eve. No more drinking Christmas morning and afternoon, just to pass out early Christmas night.
Trust me, not only can you do it, you will be so much happier and create meaningful sober memories that you will actually remember.
Never too early to start thinking of your plan. I already have mine in the back of my mind.
Congrats on day 5!
