Its called hypoglausimic. Low blood sugar levels, feeling tired, weak and sometimes dizzy.
I hate that feeling but I get it. As soon as I eat a snickers bar or anything with sugar I'm back to life. It's opposite Diabetes because I need the sugar whereas diabeties can't have sugar. My body apparently doesn't produce enough insulin.
I'm an electrician for 14 years,and I walk my dog 3 miles a day for past 4 years. Now I got into chopping wood. lol Excersise doesn't help...the body is made the way its made. Sucks.
