I am right there with you Redline. I started about 5-6 days ago as well. I had a great workout this morning, but this afternoon I feel a little tired. I tried to eat more PB carbs today, such as bananas this morning. I am getting between 60-100 carbs per day. It could be just the adjustment to the change in eating and few carbs. I was getting up to 250 per day in my normal diet.
