new to group

Hi,

I just found this group on the OH site. I had RNY surgery on 7/21/09. Just had my 6 month check up and dr. stated that my 1 mile walk during my lunch at work wasn't enough. He wants me walking at least 45 minutes at one time, he did state not to stop doing my 1 mile walk, just had another 45 minute walk in.

I am having trouble doing that as i get up at 530 am to go to work and don't get home until 7pm which means it is dark when i get up and dark when i get home. I don't have a treadmill, any suggestions??
