Three weeks down

Today marks three weeks since I haven’t had a pop. I am debating weather or not I can drink one when we go out to eat or something now, cause I know that I can do it so just one or two a week would be ok, so I don’t know yet…do you think I should have one or two a week? or do you think that I will fall back into my habit of 5+ a day if I start with one or two a week?
