I wanted to offer my voice of support. I have started and restarted a few times myself. My first weight loss 350 to 280 was so amazing that I fell off the plan. I got scared. I gained to 325 and started again. I found myself at 190 and again got nervous.
Now backed with a counsillor I started again from 200 and so far I'm doing ok. No fear. I think it helps that I'm exercising more: dancing, walking and such so I like how my body moves. It helps alot!

Sorry I rambled. But my point is this. Keep trying. I noticed my downward weight loss. Be sure you are getting all your vitamins because that makes things easier. Just keep on trying. Low carbing isn't perfection. Its a tendency. I mean one day off and 6 days on won't hurt you. Not if you keep trying. Seriously though, stay away from sugar. I found that alone will cause me my addiction to go double time. I can handle a roll but not sugar. Just a thought.

Take care - I'm here for you
