TIRED
I don't know how to explain it, but for most of us it is common for about one month out to fell like you have hit a wall. Your body has been trough a lot and it takes a bit to catch up. Make sure you are taking your vitamins and make sure you are getting in all you fluids. If this keeps up call one of the dietician. Make sure you are getting a nap if you need it. Just give it time you will being doing better soon.
