Jody I know what you mean about feeling like a hypocite . i'm an ANUM on a medical ward and I feel awkward about giving advice, especially to diabetics ,telling them to change there diet and exercise..
Sonds like you are doing a great job to be able to fit into size 10 jeans, i'd be happy to get into a 16 at this stage
Some of girls on my ward, go for a walk at lunchtimes ,but its hard when you only have 1/2 an hour, when I go to the gym I go directly from work or first thing in the morning and the same with my swim or a walk, but it is certainly hard for you with the kids. hope you work out a plan
some hospitals have a gym, not ours its not that big, how about yours
