HI and welcome!
I would reccomend you use the next several weeks to thoroughly get your head wrapped right around what you are about to do. Mentally prepare yourself will help you immensely.
By doing so, you can start the diet with an overflowing level of commitment, which is what this diet requires.
Do it with a 100% attitude, and you will soar through it. Commit to sticking to it 100% and it will be done in a record amount of time. If you lapse, and start playing around with it, you will struggle.
Once you are "in it to win it", the world is your oyster, and nothing will stop you.
A good, strong mental attitude is essential. You will be at social events, birthdays, holidays etc., where there will be food, and if you start accepting you will not be participating now, will give you the strength you will need at the time.
Its an amazing diet. It changed my life, and countless others. It feels scary at the start, saying goodbye to food, but it becomes amazingly easy. And it is all temporary anyway....and at the end of the day, "Its just food".....and you will be so glad you did it!!!!
Good luck!
