Hi Mike,
I HAD ALL THE SAME THOUGHTS AND QUESTIONS, THAT YOU HAVE. AT THE PRESENT TIME I AM HAVEING A SMALL SET BACK BECAUSE I'm eating to much. But I will say no mater what you think. I myself would go through it all, every week of my life if need be. I have so much energy now and feel great since I lost 8" off the waist, and lost 40 Lbs in the last 4 months. Trust an old timer you must have faith in your decission, and go forward, never look back.
