I went through the same thing. And all the advise I got was the same. Stalls happen, and most people when they spoke about timelines of stalls were the same. Its the waiting it out, that is hard, its the believing that it is all part of the process. Its in the desperation of thinking Oh God I went through all this and I am going to fail and then starting to lose again and feeling relief like no bodies business. Stay the course the stalls are important. they Help your body cope with the weight loss. I had a stall for almost 6 months, I thought I was done. And Started loosing again.
Good Luck.
