i guess you would know to check into sleep apnea, but besides investigating sleep apnea have you ever tried melatonin? It will allow you to get back to REM sleep even when apnea occurs.
melatonin is nature's anti-stress hormone because it counters the effects of high cortisol. many scientists consider melatonin to be the best anti-oxidant known. it crosses all membrane barriers and is a powerful scavenger of free radicals.
i take about 3-5mg about 40 minutes before bedtime. on high central nervous system workouts like heavy squats and dead lifts i have in my gear bag along with the citrulline-malate, whey, leucine etc... it counters cortisol from heavy workouts.
i suggest you start with a low dose when first trying it and build from there, because it may cause vivid dreams or nightmares in some. that doesn't occur with 1-3 mgs and like i said it helps to let you get back into rem sleep even if you awaken.
read the attached pm thread below that covers much of this. other than what melatonin does, a glass of red wine won't hurt you.
