before and after
Two not very good pictures, but one is from Feb. 2001 and the other is from August 2006. All I did was control my blood glucose, strictly.
I had morning fasting blood glucose readings of 105, 106 and then 116 after giving blood, but this morning it was down to 95 again. I didn't try to swim or run fast this week, but my bike ride today had some tough hills (and a temperature of 44 with a wind averaging 14 mph and gusting to 39) and I didn't feel any difference due to giving blood.
