Oh please. stop relying on the supposed medical expertise of physicians who far too often misdiagnose and misprescribe. Waiting till 8 AM the next morning? What planet are you on? If you wait to see your own doctor it could be days or weeks if not a month or more. People who have had a sinus infection or a yeast infection in the past know what they are dealing with. They know what they have been previously precribed. Why should they have to suffer for an unknown period of time with a recurrent illness they already know how to treat?
