What are you eating and drinking (NA) during the day, and how much exercise are you getting?
I am a huge believer that what we eat manifests itself in our thoughts and feelings - and most of us don't eat the way we want to think & feel.
Everyone is different but for me, a good nutritional day means a lot of fruits and vegetables, frequent small portions of high quality protein, good carbs like soba noodles or brown rice, and of course dessert(s)!
Then there is exercise. It is just so good for sleep!
Anyway, until you can get back to the doctor, which sounds like an excellent plan, play around with some great food choices and see if that helps.
Best wishes to you!
