Im natalie. Well I've been around diabetes & I've seen the downs of it w my grandma. I use to give her her insulin & do her blood sugar everyday for two yrs. Well now I have a boyfriend who has diabetes. He's very stuborn about his diet & doesn't want to change his diet. I've also noticed he's gotten skinnier in the past week or two & has developed even darker & bigger circles around his eyes. I am worried. He smokes & occasionally drinks!! He is 23 & im 20. Please help!!!!
