Well here I am on day 7 of Sole Source, and I have to say that I am TIRED. Not only am I physically tired, I'm also fighting a great deal of mental fatigue. The physical tiredness I don't mind so much, but the mental fatigue is starting to become bothersome. My job requires me to be mentally sharp, and it's definitely been affecting my performance for the past couple of days. Does anyone have any suggestions that might help? I've been taking my shakes on time, and have been pushing the water and green tea, but it doesn't seem to be helping much.
