Can someone tell me which Dr. they prefer Sanders or Lester. I am going to one or the other on Saturday and just want opions. I know Sanders charges $35.00 for an office visit plus prescrition for 30mg phen for a month and Lester charges $100.00 for an office vist plus gives you 2 months of phentermine. Does Lester do blood work, etc? Can someone please let me know your preference?
