symptoms of diabetes, and how to tell

recently, like over the past few months i have been eating ALOT, as in way more than a normal person should. I'm not just exxagerating about this one. I am 5 foot 7.5 inches and weigh 165 and am female. I have been eating close to 3000 calories every day for literally months. All i want are sweets. I have not gained even one pound. i crave sweets all the time. i get into weird sleepy/trance like after i eat these big meals. and even more recently i have been SO thirsty all the time.

It sounds like you might be diabetic. Go see your doc and get some blood tests done, then your doc should send you to an endocronologist if something is out of whack in your system or you have diabetes so that you can get on some meds and have everything leveled out.
Also remember it is important to eat healthy. Have balanced meals.

It sounds like you have some classic diabetes symptoms, which include tiredness, thirst, hunger, unexplained weight loss, blurry vision, frequent urination, dry cracked skin, some mental confusion.

A blood test by your doctor will only take about 5 minutes and is usually quite accurate in assessing if you have diabetes. See your doctor sooner rather than later.
