Welcome back. I'm not much of a poster, but I had to reply, because I am a fellow Sims player (assuming that you are). LOL
I have pretty much the same story as you. Lost quite a bit of weight - hit a wall with my gall bladder that I eventually had removed, and worked my way back up the scale.
I commend you for stopping the madness at the point you had begun your weight loss before, as the 50lbs that I have just lost put me at the point I began the last time when I lost 70lbs.
Good luck...and I am here if you want to chat.
