Just a thought for Monday with reg doc. If he won't agree to Ambein or something in that class of drugs. Ask him/her for Atarax, generic is hydroxyzine (spelling?) it's basically an antihistamine, non narcotic. It works for me when nothing else will.
Maybe you could ask about this& hopefully it will be ok with your other meds
Insomnia is almost a nightly thing I deal with but don't have the bad dreams & thoughts during sleep.
This is ONLY a suggestion & only if you feel comfortable asking.
Just hate to see you suffer so much to get some sleep. I am not a T or a doc.
Hope this helps!!
