Welcome to the community! Great work on 4 days 
This is a great community to be a part of…I spent a lot of time here during the early days which helped me stay sober. Many amazing threads to read through for support and advice.
The Checking in daily to maintain focus #72 thread is a great space to check in as many times as you need for support and accountability.
I am not sure of your drug of choice…try to have a clean space so you are not triggered and don’t have easy access.
If you are attending gatherings for the holidays - try to have an escape room or are able to get away if you become overwhelmed.
Have something in hand so you are not offered a drink.
Check out local meetings for AA or other recovery groups so you know what’s available and where (may even be online).
This place is active all day everyday day so you’ll always find someone around.
Take it one moment at a time…try not to think about past mistakes or future events, what ifs…just get through the moment at hand. As long as you survive the day sober you have won!
Happy to have you here with us.
