Difficulties with sleeping are a very common symptom of bipolar - make sure you describe them at length when you talk with that clinical psychologist. If you have a number (67 hours awake), give him or her the number. You cannot work productively after having been awake for 67 hours - make sure it is in your record.

I know nothing about Latuda, but Tegretol and Lamictal by themselves are not supposed to help with sleep, as far as I know. You need something else. I don't understand why you had to call your doctor 4 times; not sleeping is an urgent need; when my sleeping pill stopped working and I needed another one, I was seen by an on-call p-doc at my clinic the very next day after I called. They should not be leaving you hanging and not sleeping. A NP is perfectly well equipped to prescribe a sleeping pill for you - you do not need a doctor for it. Be very assertive though when you call and say that not sleeping is absolutely not OK.
