Today is a new day that you don't have to drink.
If you don't mind me asking, what did your sponsor tell you? It could help other's if you share. As to why he was right, I'd guess because he is your sponsor and has experience that you don't and may be able to see thing in you that you can't. Of course that is without knowing exactly what he said.
In the long run unhappy sober is beter than happy drunk. Take care.
