The sleep specialist I know said the important part of good sleep is the time you get up in the morning. The brain controls the sleep cycle and rarely uses much sleep beyond a hour or two after first light in your room. I have always been a night owl (it's 1:15 am) but I wake up routinely at 8 to 8:30, sometimes 9 am. She said there definitely are night owls and early birds but early birds get up at 5 to 6, maybe 7 while night owls should be waking up 2 hours later or so.

But, she said the most important thing is to sleep the same hours and times each day so the brain's sleep clock is not disrupted.

What vitamins are you taking already ? How much Vit C are you taking ? The B's are the most important plus good fish oil.

btw, Stomach issues can manifest from lower neck injuries. CT's and MRI's rarely show these subtle neck injuries. Some specialists can diagnose them with chiro or osteopathic techniques. Other times, you need to try a treatment protocol and stay with it for a time to see if things improve. Prolo therapy can help if the therapist can first diagnose the problem location. No use treating an area that is not injured and miss an injured area by a few centimeters.

I saw a TMJ specialist who wanted to sell me an expensive appliance, but I finally found a physical therapist who used in the mouth pressure points and such and helped me get relief. I was locked to only an index finger width. She got me to two fingers width and over time, I am almost three fingers width.

For clenching, there is a Botox protocol that weakens the jaw clinching muscle to allow healing. I was about to try it when I found the PT.
