I'm so happy you got good news!! I wish you the best and August 10th is just around the corner. Continue to pray and stay strong. The payoff is amazing!!! You asked when did I start exercising. My surgery was 12/13/11. I started to fill strong enough to walk after my 3 month checkup in March. I walked 1/2 mile for three days then 1 mile the next three days. It was hard and I was out of breathe but the more I did it, the easier it got. So, I pushed on pass the itching and aches. By the end of May, I was up to 3 miles 5 days a week. I saw a huge weight drop and pushed myself to five miles 5 days a week. Well, it didn't hurt anymore and my body was used to it. At my 7 month checkup July 13, 2012, Dr. Yu said congrats you've passed your goal. Now I do three days a week and I'm still losing. It's slow now, about 3 lbs in 10 days.
I will pray that you get through your surgery with zero complication.
