Advise?

I am just starting out on this app after losing 8lb without it in 2 months, I weigh myself the 1st of each month.

I an using meal replacement shakes at the moment, not as a diet as such - though they are a cheap version of slimfast. This is solely because I just had a wisdom tooth out and ended up with a painful dry socket. I ended out feeling really sluggish and awful and they help. I get my next tooth out in just over a week. Once I'm all healed up they will be gone.

Anyway my question is, what kept you motivated, committed?
