I am thinking about giving blood this week at a Red Cross drive this week. I am nervous and all, but I am also not sure if my diabetes will be a problem. I am not severely diabetic, like I am not on insulin. At the moment I am trying to control it through diet and exercise. If you have any ideas I d appreciate it. Also, if you are a blood donor, can you help relieve my nerves about giving as well. I d appreciate any help and advice possible. But if you are going to be stupid, save your time and don t answer.
