Di,
I hope you doctor can help you get on something to help with sleep. I know that klnopin will help me sleep but with a hangover the next day. Most people I know though don't get the hangover because they take theirs everyday I suppose and I take mine as needed. I'm like you though, I wouldn't know how it would react with all the other medicines your on.
I do get creative at times like Curious does when I'm up all night.
Hang in there.
