Great work! a LOT of us have gone down that same path and can relate to the challenge of getting there. I lost 60 lbs, put back on about 15, then dropped 20 over this past Winter/Spring to get to my lowest weight since college. I too hit a plateau but was able to push beyond it by really figuring out where the extra unneeded calories were coming from and then cutting them out, along with reducing portions. Those hills are going to feel much better as you get those pounds off. Keep it up!
