OP, I understand the feeling of accomplishment you are experiencing. My story is floating out there on the forum somewhere, but I hit the gym literally the day after I FIRE'd, and with some significant dietary changes I lost 60 pounds of my own. Yes, one of the hardest journeys a person can embark on...but it is the difficultly of the challenge that makes the sense of achievement such a powerful one.
Congratulations. I love hearing stories like this.
Not sure if you are FIRE'd or not, but if you managed to do this while still working, then my respect for your accomplishment is even higher. I couldn't get a grip on my health and fitness until I left the job site behind for good.
