Zeta Posted August 8, 2015 Report Share Posted August 8, 2015 I've suffered from early waking insomnia all my life. Until a few years ago, it was fairly minor, and manageable. But a few years ago, in connection with some other andropause-like changes I went through, I started to wake and not get back to sleep after 4-5 hours of sleep instead of 6-7 (8 hours is optimal for me). I was also losing weight, though I don't think I was eating less. I think I moved into an aged phenotype all at once. (Long story there.) Regardless of the strange changes that took place a few years ago, the early waking, which was always a problem, became worse. I've had my early morning cortisol tested several times over the last few years, and it's always been above the reference range. This is no big surprise for a person on CR: low blood sugar causes an increase in cortisol (which keeps blood sugar from falling "too low"). It's not that I'm tense, it's not that I'm hungry (well, I am, but I always am). I'm just awake. Well, my 2:1 diet plan has yielded some interesting results. The night after Feast Day 2, I sleep beautifully! The night after Feast Day 1, I often sleep fairly well. The night after the fasting day (right now around 700 calories/day), I sleep worse than ever. I wake too early, and can't get back to sleep. I'm happy, non-tense, not really hungry even. Just really awake. So now I'm thinking I might take timed-release zolpidem or something on fasting days before going to bed. But I'm wondering if anyone else has tried any cortisol lowering strategies that have helped with sleep. A lot of supplements that supposedly lower cortisol seem to do so (if they work at all...) by lowering stress. I'm not stressed. Phosphatidylserine blunts the post-exercise cortisol spike, but it’s not clear it would help with low glucose-induced cortisol. Suvorexant might be a better choice than timed-release zolpidem (or one of the other Z-drugs), but I haven't studied the relation between orexin and cortisol enough to know whether it would help me. Any CR folks with early morning insomnia have any strategies they'd like to share? Link to comment Share on other sites More sharing options...
