well three days is a start, i personally would not go COLD turkey on stuff just reduce the amount gradually until you don't even think about it, i try and do that with all things really, food and coffee mainly at the moment but i failed hard at that this morning when i had two coffees back to back at the co-working place because i had to salvage the day!
It is a little different with alcohol, I think. I have tried reducing the amount I drink, but to no avail. That first drink is like opening a gateway to eternal dissatisfaction. After having one, you feel like you won't be satisfied until you've had a second, but after the second, you feel like you still need a third in order to reach that. I have to avoid it entirely and completely cleanse my body of the ill effects before I can attempt to control how many drinks I have in one night. Plus, I want to get rid of the cravings. I want to consume alcohol for the occasional celebration, not to soothe a nightly craving as I have been.
fair. all the best with it! hope you find a path through!
