This isn't a good indicator for me either. You say you placed your order on the 16th, another said they placed theirs on the 14th and I placed my order on the 19th, so I most definately am not going to get mine anytime soon - AND I paid the extra $$$ for the faster shipping too!
I am human however, and I realize that it is the worst time of year for shipping of any kind with the holidays and all so besides them being swamped with orders, the USPS, FedEx, UPS and others are absolutely swamped too. More people then ever are ordering gifts online so the shipping this season must be breaking all-time records.
justincase don't beat yourself up about it either. You have done well in quitting and this is only a short/temporary setback. At least you've already proven to yourself and others that you can do it!
One good point was made however and that is to always try to keep an "emergency" supply handy just in case. - (some of us have too much of an emergency supply)...
