CONGRATULATIONS, NELIE! I know how frustrating a plateau can be -- I just broke through one of those myself!
I'm really happy for you, and proud of you for riding it out. They say that shaking up your eating and/or exercise routines can really help, so in case you didn't know that, file it away should you run into this plateau nonsense again. (That's MY plan!
As for the water, good job! You'll get used to it before you know it, I promise. Just stick with it.
Again, great job and CONGRATULATIONS!
