More often than not, the members of this forum impress me with their can-do/ take charge attitude.  ZolliStar's response on a vitamin thread that I just came across struck me as representative of the attitude that I set out to encourage in people when I started the forum years ago.  Keep at it ZolliStar -- you're doing the right things!  Here they are, in her own words:

Also, thanks to discussions on this board, I've made some important changes/adjustments. It's too soon to say for sure, but so far, they "seem" to be helping. Changes include:

• A brisk 30-minutes walk mid-day in sunshine. (Thanks, to Rock for posting this: https://www.youtube.com/watch?v=aUaInS6HIGo).  Also thanks to Dr. Steven Park's Sleep, Interrupted that specifically recommends walking (or other exercise) in sunlight, preferably mid-day when sunlight is strongest. (I also recommend his book, btw.)
• Eliminating alcohol. (*Sigh*)  The upside: I'm saving money.
• Caffeine -- cutting it down or out. This includes eliminating chocolate, which I adore. I've simply decided to turn my back on it. The upside: I like the really good stuff, be it coffee or chocolate, so (again) I focus on the upside: I'm saving money.
• Computer use: I've cut it back in the evening BUT (thanks to advice on this board) I've also installed the F.lux program on my computer. It's supposed to cut back on the blue color off one's monitor so that it's possible to use it later at night without affecting or afflicting one's sleep. (The color change after sunset is noticeable, btw.)
• "Powering down" at night. I start lowering lights about 9:00 pm, I quiet down reading and relaxing.  
• "Sleep nutrients" taken at night. Melatonin (2.5 mg) and Tart Cherry Juice (1 tbs.) Tonight I'm adding the Vitamin C (2,000 units), Calcium (2,000 units) as well as magnesium.

Last night, to my astonishment -- and I had done all the above except the very last (which I'm adding tonight) -- I started YAWNING BY 10:00 PM!

I'm still not sleeping really well or deeply, but I'm sleeping much, much better. I recognize that this has elements of being a lifelong journey. So be it.

I wish I didn't have OSA but given that I do, I'm grateful for two things: my diagnosis (after so many decades) and SleepGuide.com.  Kudos to Mike and Mary who do so much for us all!
