Come on last 5

So I am new to this, hi ladies (friend of Sarah and Andrea's). Let me tell you- I lost 35 pounds, and have really struggled with the last 5 I want to drop. Do you know what it is like being a Home Ec teacher and being surrounded by chocolate chip cookies and pizza all day every day? So I am trying to avoid snacking in class. Next year will be different and I can actually teach nutrition (I just took over in March until the end of teh year. Not my curriculum plan). So starting Monday I am going to ride my bike the 4 miles to work (and 4 iles back, of course) at least 3 days a week, if I can. And one of the other teachers and I started to walk on our prep hour because it is exactly 1 mile around the school property. Maybe that will help. Problem is teh AZ heat starting to rise. It's tough to walk at 10:30 a.m. when it is already 95 degrees. Yikes! Walk on, though, walk on........
