One of the things that changed in my regime in the beginning of December was Biotin. I had just added it in, then I slowly increased my dosage. I believe it helped me to dry up, and most of the weight I lost was water. I thought I’d put that out there just in case you weren’t taking it.
I’m sure your thyroid will recover, and you’ll loose more weight. I just keep focusing on the body’s amazing ability to heal itself.
