I am guessing I must have lost too much water the day before. Will need to say very hydrated today. When working out I like to take Aspirin as it not only gets rid of your headache. It also thins the blood and you can carry more oxygen to your muscles, thus stimulating more muscle growth. Of course this in turn helps with a higher resting metabolism and consequently more weight loss.

Day 2 Weigh in.  167.8 lbs.  I must have cleared out my system a little bit the day before.  I would imagine this may go up and down a little in the next few days.
