I go today at 2:30 p.m. for deep cleaning. Opened my Amox pills and they smelled funny. Looked, expired Jan. 04 I knew they were old. First, March 17, 2003..but that would still made them expire after 9 1/2 months...of course, I called and will pick up new ones this morning.. I take 4 500 mg..as I'm sure all of you do the same..before cleaning..Bonnie
