Diet Challenge, January 5

I did well starting off yesterday and exercised twice. It will be more of a challenge on weekdays. I am going to try to sign up at the new Curves this morning, their first day to open. However, only if I can get the contract to work how I want it. If I miss a month due to health issues, I don't want to pay for that month. How long can I go without attending and not pay the start-up fee again? Can I let someone use my membership if I'm not there? If they can answer these things correctly, then I'm in.
By the way, I am keeping a diet journal this time, to see if I like it. I hope it will keep me on track......
