Obviously working won't make you gain weight. The stress and shorter amount of free time may influence how, when, and what you eat, however. If you feel you can handle the loss of free time, and if the financial incentive is worth it, by all means give it a try. You sound like you're aware of the possible pitfalls. Be diligent and you should be thinner and richer in 8 weeks. Good Luck!
Life style change started on Jan 13, 2011. I was going to lose 100 pounds by Christmas.
I lost 93 pounds by Oct 1, 2011 and am holding there for now. We'll see what happens.
New goal: To maintain at about 160
Final Goal: To decide if I need to lose more
Just Keep On Keepin' On
