These type of things are 'normal', as your body starts to deal with the waste, and ready to be eliminated. You will feel tired some times, and this is because your body's system is not functioning /working properly, and one of those functions -- your energy management -- is not working. Now you are not eating the same as before, and your body's system is not being stimulated from chemicals.
You have to let your body do what it's designed to do, and these things will pass.
Soon, you will start to feel more 'awake', and you will start to have more energy.
Stay with the programme, and you'll be in the best shape that you've ever been. And, you will have more energy than you've ever had. You'll be able to run around like a 10 year old girl.
Your body will reverse your health condition, and as long as you allow it to.
YOU don't need to ask anything other than regarding your health programme, and I will not reply to any comment about ANYTHING ELSE.
I do.. And I don't need permission from you, or anybody.
