Feeling fantastic but tired today. I have found this week (week 4) that I am a lot more tired than normal. So far I have lost 8lbs, 2 inches off my waist and my next weigh in is Sunday. I am feeling fantastic today though as at last nights gp referral gym session I ran on the treadmill for the first time. It has always been my fear as I could just see me flying backwards across the gym. Last night I thought what the heck and nailed it. Now my goal is to build up the amount of time I run on it, I'm buzing. Had to share my triumph!
