My journey goes to show you that it doesn't matter how many times you fall off track. What matters is making a choice to get back on. You need to be realistic, don't expect not to fail. Don't expect to lose it all right away. Don't expect it to be easy.
Wow! That's fantastic! Congrats on reaching your goal! I can't imagine how good you must feel right now, although I hope to be able to feel it one day soon!
