... warning signs, he gets insomnia and was on adavan and ambien which he said was not helping and i found a suboxone in his things and he swears he is not doing drugs again that he got it from a freind to help him sleep, of course i know this is bogus and he is not on the program, what i want to know is if anyone could help, i have some questions, first of all can it make you sleep, can it be abused to get high, and is it likely he is substituing the suboxone because he ran out of drugs so he doesn't go into withdrawl? thanks for any answers you can give i need a full picture so that he can't continue lying about not doing drugs again.
