David,
I can relate to your position as well as I am now 9 months post Tx and still 30 pounds lighter. I was diagnosed just about a year ago, 4/27/06, and at that time weighed 185. I lost a total of 40 pounds, down to 145, at a point around 1 month post Tx. This loss also involved a 4" waist loss and required the purchase of all new pants/jeans.
I have managed at this point to put about 12 pounds back on even though I seem to eat up a storm. It puzzles me also and I mentioned it to my Rad Doc back at the time of my Dec. follow-up and he didn't seem concerned or offer any explanation. He felt that I should just relax and get used to the new weight and enjoy it.
I do know that I don't snack like I used to mainly because my taste buds are still screwed up. None of my formerly favorite snack foods taste the same such as Fritos, Cheetos, pastries, etc. and I just do without. I am now addicted to Skittles but they don't seem to do much in the weight gain arena.
I have decided to quit being concerned about the weight situation after all. I guess I stopped and listened to my Rad Doc when he asked me why I was concerned about it. I told him because it had been "normal" for me to be around 185 for so many years. He then asked me if there was anything wrong with my "new normal".
