Hi, I have a couple different symptoms that have been going on for a few weeks and I am trying to see if anyone can relate to these problems. All right, I have been really tired for the last 3 weeks, even when I sleep well at night I am still tired. Every time after I eat or drink something with sugar I get this weird feeling in my arms where it is really hard to lift them and move them. I have been tested for diabetes and I don't have it, but I am also concerned, because I wear glasses and notice that I am squinting with my glasses on and I have trouble seeing things with my glasses on. I don't know what is wrong with me. I am thinking it is either a blood sugar problem or like pre-diabetes or an insulin problem, because I get all shaky sometimes after I eat a candy bar or drink a lot of pop, but this does not happen all the time. The thing I am most concerned about is when my arm gets all weird like it is hard to move and feels like there is some chemical problem in it. If anyone know's what this might be or can relate to this problem, please post a response. Thanks-matt
