My husband has diabetes and is now having a hard time keeping it under control, how do I make sure we control his diabetes?

e, about diabetes in general, he has been getting better about checking his sugar, and trying to be the clumsy person he is, and constantly getting hurt! things I know dont heal as fast as they would if he were not diabetic..... I have a house full of food that Now I am realizing, is killing him! Like carbs, sugary snacks etc,,,,,,,,,,,, I need some knowledge on this desease, as I have been so wrapped up in my moms, that I have sorta neglected his, not thinking, that it is as bad as it could be, he also has a very dirty job, which is fine, but now I see the importance of keeping hygiene a MUST for diabetics, I am on my way to the drugstore, until he see's his doctor on Tuesday, to get some topical yeast infection creme that I use, so he doesnt itch off his privates, also new toothbrushes, and glucose tablets, when he watches what he eats, and takes his sugar, it seems to help, but I cant make him remember to take his meds, etc,,,,,,,,,, I set up the trays and just hope he wont forget,
