Well you are certainly in the right place both mentally and physically. Physically you are here with us and we are here to help you, I sound like an evangelist, sorry. Mentally, you have been through it and you are ready to put things right. You should be able to achieve everything you want on this diet. It is not a miracle worker but pretty near to it. At least medically your life will improve even if we can’t improve your love life, that will come.
Enjoy the journey, it is well worth the effort, the carb blues, the hunger (although not for me) and the flak you will get from your doctor. Put a message out to all of them, you are doing this for you.
Good luck.
