My husband went "carb" free in February, and he has lost about 2 and a half stone, I decided to follow suit in May and must say it is going terrifically well.
I no longer get dips and "highs" from the sugar, I am far less lethargic during the day, I sleep soooo much better, I had had a cough for quite some time and did some google research to see if there was a connection between the coughing and sugar and was surprised to see that there was. So, so much better all round I would say. I do not get hunger pangs, or cravings for anything, thought I would seriously miss bread/potatoes/pasta, but not one little tiny bit.
I would say go for it, nothing to lose, except some unwanted weight.
