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. found in the vitamin section of every grocery, dept store etc... and it's inexpensive.
GABA helps me fall asleep, but won't keep me asleep as melatonin and L-theanine will do. pramipexole can be found at peptide/research liquid sponsors of professionalmuscle.com and even low doses will make you very drowsy. do the research.
prescription hydroxyzine pam 25mg capsules are cheap if you can get your doc to prescribe. the last thing you would want to consider is low dose alprazolam/xanax 0.25mg or 0.50mg at bedtime, but those can become addictive.
op other disruptions you may also be aware of:
Light level and duration of exposure determine the impact of self-luminous tablets on melatonin suppression. - PubMed - NCBI
lastly keep your bedroom as cold as possible.
P.S.
i worked on a sketch of myself below to show the proper sleep position. hoping to become a "featured member" and get alin sponsorship soon.
