I do snore I think but not excessively (my wife is far worse!) . I do tend to be a mouth breather. I'm maybe a tad overweight. 5'11".180 pounds. I don't feel particularly tired and sleepy during the day and have quite a lot of energy really.
I am 63 and still working - as a writer. I do get quite stressed.
I have had a bit of a virus recently and felt a bit shaky during the day which may have exacerbated things at night.
I'm on statins (rosuvastatin 10mcg and was recently diagnosed with Hashimotos disease, which was asymptomatic, so am on 50mcg levothyroxine.
Hope this helps.
