K.N.
Is he a big snorer or a heavy-set guy? My husband was diagnosed with sleep apnea in the spring and now uses a CPAP machine when he sleeps. Neither one of us can get over what a HUGE difference it makes in his energy level! He can stay awake for much longer now, remembers conversations better, is much better company & just enjoys his life more.
Ask him to talk to his doctor. My husband put off and put off the sleep study, convinced it wouldn't do any good. He was so very glad he finally did it!
