I'm going to see a neurologist/sleep specialist (the person I found is both apparently). I just saw my psychiatrist and she didn't think she could help with my sleep. Which is actually fine IMO, because she does have a lot of other stuff to keep track of with me in terms of meds, and I'm not sure exactly what she could do. She doesn't have testing equipment or anything like that.
I have a completely different problem than frank insomnia. I can choose between insomnia and a semi-normal sleep schedule or heavenly, wonderful sleep and sleeping during business hours. I've already done blue-light, orange glasses at night, going out in the sun and exercising early in the day--every sleep hygiene thing I can think of. And I still do them in spite of it not seeming to work. Only thing I haven't tried is melatonin because I already have so many meds on board and don't want to add anything that could interact. My psychiatrist thought melatonin was OK to add but wouldn't say so definitively, so I'll wait till I see the neurologist/sleep specialist.
I feel guilty every time I let myself get good sleep because I know I'm getting away from a normal schedule. But when I stick to a normal schedule, I never get used to it and feel miserable.
It's a frustrating problem. People think that if I just wake up earlier I'll fall asleep earlier. But in truth I suffer through the fog of insomnia all day and then my brain clears out in the middle of the night and I'm finally awake. I've actually been curious if I were to move to the time zone I'm in sync with whether I would be "normal"--not that I would do that, but just wondering hypothetically.
