urges and drinking plan

So Yesterday I had a drinking plan for 18oz of wine at 6:00 when my day was done. I started feeling urges at 3:40 pm and they really stayed up till 6:00 when I planned to drink. So obviously I am counting the urges. Here is my question: Is it okay to begin my drinking plan at the time I planned for it even if the urge is still continuing. Obviously, the urge left and I payed attention to how I felt during, immediately after and this morning.
