Hang in there.
This seems to be the story of my life lately. I had a couple of weeks go by with not much changing in either pounds or inches and then, boom, a visit from the mythical Whoosh Fairy and I wake up 5 lbs lighter!
Then other two weeks of very little movement and, bam, another 4 lbs gone.
I have to add the universal qualifier, YMMV but I'd thought I let you know that others have had your frustrating experience and it can indeed have a happy ending!
