Sadly lammie your wasting your time and breath trying to tell him to stop drinking energy drink or full sugar anything he just wont listen to reason about it, There's stubborn and then there's Hotrhymez he seems to think nothing will ever happen to him ... I have tried for years now telling him about it and even proved what to much sugar can do and still he doesn't try to reduce it so I told him fine stop saying how tired you are then. If your not prepared to even try and cut it down or out... He says I'm nagging so I gave up at that point....now his on his own with it.. His up's and down's.
