Just like the previous person said - You CAN do this!
I understand what you are going through. I went through 3 bad days at the beginning and took Advil and not Tylenol to get me through, but keep it close by. My coach was awesome and called me everyday for the first 4 days to make sure I was doing well and helping me out with any problems.
I did fall "off the program" about a week ago and went through the headache and tummy problems for the first day, but the next day was fine.
You can get through the bad days and in the end feel incredible and have the energy to keep up with your kids and family.
We are hear for you! Good Luck.
