Well it is all well and good to say get more sleep but if you suffer from chronic pain that is not an easy thing to do. I have tried most everything and nothing that I can use helps much. I have tried the drugs like Ambien but those give me the worst vivid dreams you can imagine and it takes hours to overcome the effects.

When I have missed a lot of sleep I can load up on pain meds and muscle relaxers and get a long nights sleep. If I take nothing I might stay awake 36 hours at a time. So for some people getting sleep is simply a major problem that is not easy to overcome. I avoid things like caffeine and have tried numerous drugs and natural remedies and they do not really help. So telling someone like me to get more sleep is laughable and useless.

I am a third shift worker who works from 11 p.m. to 7 a.m. for 5 nights per week. I am lucky to get 4 hours of sleep per work shift. I have tried so many different techniques for getting more sleep but nothing has worked. Do you have any suggestions for third shift workers? Thank you!

My husband suffered from lack of sleep as well after years as a musician. I just learned about these a few months ago, and they have really worked for him. I saw the founder speak at a local conference and was impressed by both the story of the company and the non-addictive all natural ingredients used. You may want to give it a try.
note: I do not have any affiliation with company, just know it help my hubby a bunch.

Have you tried valerian root as either a capsule or infusion(tea)? It makes me relax and sleep.

There are many people with sleep apnea who have not been diagnosed or received treatment. A sleep medicine physician can diagnose obstructive sleep apnea using an in-lab sleep study or a home sleep apnea test.

It’s also worth noting that people who are “long sleepers” are at increased risk of morbidity and mortality. (In some studies this is defined as sleeping more than 9 hours a night.)

In other words, sleeping longer than 9 hours a night could well be a marker, but not a cause of increased morbidity and mortality.

From a meta analysis:

” . . . sleeping 9 h or more per night may represent a useful diagnostic tool for detecting subclinical or undiagnosed co-morbidity.”

Interesting article. Would you happen to have a reference supporting the following statement: “In fact, 18 hours of continuous wakefulness has the same adverse effect on reaction time as being legally drunk!”

I’ve seen similar statements but have been unable to find the source.

Thank you in advance!
