I do have IP documentation that says you can have up to 5 packets a day in the first week to deal with hunger. Still only one unrestricted. This is old and not sure it's still relevant, but certainly 4 is allowed that first week. Also, if your goal weight (not starting weight, and not current weight) is over 200lbs, you are allowed more packets per day, one more for each 40lbs over a goal weight of 200.
