Stall......

I know is normal, but any tips on how to break a stall????
I am 6 months out, i've lost 80 pounds, and I know is great, but i still need to loose 20 pounds and have been in the same weight for 1 1/2 months.....Do you think I'm done loosing?

Thanks!!!!!

 It is normal.   I stalled at eight months out and thought I might be done.  I stayed at 174 for what seemed like FOREVER.  Then I sort of quickly lost another 30 pounds.  I stayed there for a few months and now I have lost another couple of pounds.  
  I am 16 months out today and I seem to be losing again.  Slowly, but it is happening.
