Debbie, the first thing I can tell you is to read other people's journals. You will be so surprised at how much information you will get by doing this. It is a shame that your husband is not supportive, but just remember you are doing this for yourself not anyone else, and you are worth the effort.
By the way, you have already had a great start 30 pounds gone, that is great. Also I agree that weighing anymore than once a week is just setting yourself up for disappointment. That scale can be such a ugly little varment, .
Ask lots of questions and believe me having a journal is one of the best things to do, so if you have not done that yet begin one.

Best of luck with your low-carbing....joan
