Need second wind!!! Or third, or....eleventy billionth wind

Hey fit fam. Well I have been here 2 years (9 months of that I was pregnant) and am almost to my goal!!!! I have 20 (or 25, damn women, never satisfied you know!!!!!) left to go. I know I have it in me and my amazing friends on here have been a catalyst to my success so far. So, I ask, for those who have dropped hella pounds, how did you get through the toughest part, the finale? It comes off so slow at this point and I am not going to resort to anything that I cant sustain life long!!! Anyone have any tips??!!!
