Hiya,
First of all stop talking about yourself negatively. You are a beautiful person and you are ready to do something about this... These are great positive things.
Also don't be so sure you won't be able to do a fast.
Its restrictive calories and natural foods.. You can do that and who knows you might like it and incorporate it into your lifestyle regularly.
yes... you will lose about a pound a day. more than likely 2 the first day depending on how much energy you use and how tall you are...
Just be sure to listen to your body and not absorb chemicals other than coffee if you can help it...
Coffee in the morning is a great way to start the flush.
