my 18 year old son was diagnosed with type 1 3 years ago. at first he was very good with his control. july 2012 he was in hospital for a week with DKA. he just doesn't seem to take it at all seriously. i find empty full sugar drink bottles in his bedroom. he doesn't do readings , he will quite often go out without his insulin pen and reader. if i ask him about it he will lie and say he's done it. he never looks healthy what can i do?
