Personally I love the purple

Onece you increase the lamactil maybe it will control the rage and you won't need the kolonipin. Some doctors are a bit hesitant about prescribing benzodiazepines cos they are addictive and you get habituated to them if you use them regularly so you need more to get the same effect.
I know it sucks to get a med change. I used to get really upset over it but now I trust my pdoc cos he's awesome
if you don't like your pdoc then maybe think about finding one that you do like but maybe give them a chance first.
