25 lbs is terrific. Celebrate your accomplishment - it is huge! lift a weight that is 25 lbs and you will feel just how much lighter you are. It's your life, don't worry what co-workers might say or what they might think. What does it matter? Worry gets you no where!
My surgery was 1/17/12 so I think we are at the same stage post-op. I went back to work just under two weeks post-op. I was tired, but it was good to be intellectually stimulated rather than being at home and thinking about....food.
I'm still surprised you are eating solid food. I'm on liquids until 2/14 and then go to the 2 week pureed phase.
Exercise is key. Walk at least every day and if the weather isn't permitting, get up, put some music on and dance or walk in place in your livingroom, lift your knees up high and move your arms around. It will help with your psyche if anything - gotta get the blood flowing.
Think positive proactive thought as they breed positive proactive actions!
Give Thanks!
