In that intoxicating state, though we have been for ages, yet we keep pulling the thread and weaving every moment.

This beautiful couplet captures the essence of dependency and the bittersweet nature of habit. The speaker says they have been in the tavern (or state of intoxication) for ages, yet they cannot stop the compulsion. They keep drawing and topping up the flask, even though they should know better. It's a profound commentary on how we cling to familiar comforts, even when those comforts are ultimately detrimental to us.
