Shelley, I really empathize with you. FOr the first few weeks of my "serious" plan, NOTHING happened. I'd cry almost every day because it was so frustrating. I was working so hard for NOTHING!
I don't know why it changed. I think eventually I just worked harder and harder and examined myself more and by trial and error, found something that worked. Please don't beat yourself up or give up! You're really doing great. And like Nelie said, TOM is AT LEAST partially to blame. We've got a raw deal!
Hang in there, we're cheerin' for you.
