Hi Natpot,
I did not do this the first time and therefore had withdrawals which are not nice.
But I lost the plot in the middle of my journey and in order to get back to SSing as I was falling off the wagon all the time...I worked the steps and cut down on carbs and the difference was unbelievable.
So much easier and I was in ketosis in 24 hours, so if you can it is much more pleasant way to begin by cutting down on carbs and upping your water intake gradually.
