Alright, well I think it's rather safe to assume it is not diving related (fortunately enough) based on the replies. Yeah, I think I will head to the clinic tomorrow and simply ask about it.Hypoglycemia eat a candy bar. Sure sounds like it, I have been having the shakes and feeling weird all my life when I don't eat. In my case if I just work through it will go away. most of the time I stop and eat something relax and 20 minutes later it's gone. Go get a blood glucose test If it keep appearing and causes concern. Hopefully this is not Diving related.
