I think it's whatever suits you best so that you know you can 'stick' to the plan. I don't have anything but water, coke zero or Dr pepper zero in the mornings, I'll have my first pack sometimes 2pm-4pm then I have another maybe around 7pm then I have a bar while watching the tv during the evening as like you that's my 'danger' time when I'm most likely to snack! Best advice do what works for you, the weight will still come off regardless of the times you eat x
