Not sure if it is a problem at Wal-Mart or my drs. office, but the bottle always says no-refills so every month when I call in for my re-fill it seems to take longer & longer for it to get processed. It has been a week and walmart says they have faxed drs office 2 times for re-fill request. Of course by the time I talked to walmart today drs office had gone home. Anyone else having problems like this? Tired but can't sleep--I took some melatin so hopefully that will help.
