Are you still doing the same workouts and stuff? I've found having a big variety of workouts has really helped me. I think the tone it up girls have an 11 minute workout to get in bikini shape. They have it on youtube for free and some other videos of workouts so maybe check those out if you ever feel bored.
When I lost the weight last time though I think I was in the 130's forever before I ever saw the high 120's. What I like about hitting those slow moments is that I allow myself to eat more junk in order to shake up my system. But its dangerous because you may just completely fall off the bandwagon. So do that with extreme caution lol
