RAising hand.
I have had sleep issues since I was a kid. Never fell asleep easily, sleep lightly, wake up very easily. My only blessing is I can go back to sleep usually if I am awakened (a skill I learned when I had my kids).
Do you have clean sleep habits?
This really can be essential in having good sleep.
A set bedtime, and a set routine at bedtime. No social media in bed.
Reading at bedtime is allowed, but make sure your brightness on any e reader you may be using is turned down. At their full brightness they actually stimulate your brain to keep you awake.
Sleep for no more than 10 hours at any night, have a set bedtime and a set get up time, stick to this even on the weekends until you get your clock reset can take a month or two.
No Napping, no cat napping while watching TV, no real naps either.
Have white noise in your bedroom, a fan, a phone app, a noise machine, something to help buffer your brain. This helps to block out noise, and your brain will relate it sleep, and help induce sleep when you hear it.
Make sure you have good pillows, good sheets, and a nice cool bedroom that is dark.
Lastly if you lay in bed for more than 30 minutes awake, if trying to go to sleep, or waking up in the middle of the night, get up do some mundane activity, (I do laundry), then go back to bed, and follow your normal routine.
Eliminate Caffeine after 1pm.
Add in melatonin.
If all this doesn't work, and you are still having issues, then it may be time to try a sleep aid. OTC stuff is usually Benadryl, or Benadryl with either Tylenol or ibuprofen.
There are a multitude of Rx meds, true sleep meds like Lunesta and Ambien, older sleep meds like Restoril, and Low dose antidepressants like Elavil, and Trazadone. Lastly there are benzodiazepines, which are not truly sleep meds, but can work really well with little to no hangover, the risk is they can be addictive.
Being aware of the addictive nature of Benzo's I have taken them for years, if I go 2 nights without good sleep then I take one. It is a small dose, and just enough to quiet my mind, and has little to no hangover for me.
I have tried Trazadone, with no real help, and some unpleasant side effects, I did take Elavil for years for Migraines, and that did help improve sleep but not always.
Each of us is different and has different brain chemistry, and reasons why we can't sleep.
As we get older the need for 8 hours diminishes as well, as long as you feel rested it's not a problem. But if you are exhausted it is.
I would also recommend talking to your Dr about a sleep study too. We are finding that the "classic" sleep apneic person, isn't the only ones with sleep apnea. If you have elevated blood pressure, and are not obese, I recommend one. I have a patient that is actually in great shape, and had BP that was resistant to a bunch of meds, sent him for a sleep study, and Ta Da, yup sleep apnea, severe. Loves his machine, and is now off all meds for BP. I also have a young man who is "obese" by medical standards, but is built like a wrester, and had very similar issues, now resolved.
