I'm 2.5 years sober and don't have strong cravings. But when I do feel drawn to alcohol, or tempted, it's not by things or in ways that normal drinkers would expect. Like you, it can hit at 10AM. And even if the smell or sight of a glass of wine tempts me, my mind goes straight to the full bottle of vodka that I can guzzle rapidly.
I try to engage in a brief moment of meditation to clear my mind of the unwholesome thoughts and focus very deliberately on whatever I'm doing in the moment.
