I'm exhausted

Did eat dinner last night cause I got home late from work. I woke up this morning at 5:10 am and had a cup of Grape-nuts and went to SDRC to play racquetball. I played cutthroat with Dad and Eric for 5 games (I only won one game which was frustrating). At 8:00 they took off and I played a singles match with Steve Olson. I barely won that game. I played for 2 1/2 hours and burned alot of calories. I'm so tired my arms are shaking. Need to get the weight off!
