For the past few months I've been noticing that after I eat "junk food with sugar" that I tend to get really really sleepy. Almost to the point that I need a nap. I don't think this is normal because it's never really happened to me before. Any thoughts on what could be wrong? Does this sound like diabetes? I'm not sure what it could be but if this seems abnormal I know I should probably get to my doctor or lay off the sweets for a while to see if it goes away.
