My suggestion would be to give it more than three months and also to start changing your thoughts when they come in.
You are in control of how happy or bored you are.
You are in control of what you choose to ruminate on.
How about remembering how awful your drinking was instead of letting your addiction convince you it's awful not having alcohol.
Spend more time reading and posting here. You'll figure it out; and the way to do that is to not drink.
