I've had chronic insomnia off and on for over 18 years, since my second child was born. I had tried everything - sleep meds, SSRIs, all the sleep herbs, various supplements, meditation, hypnosis programs, perfecting my sleep hygiene, cutting out caffeine, changing when/how I exercised, etc. Some of those approaches helped short-term and helped me learn to reduce the anxiety that came with being awake at night, but I was just surviving, hardly ever functioning at full capacity. Brain fog was my constant companion, and I couldn't work a full-time job for years because I never knew when I would have a bad night and be unable to function the next day. Six months ago, after a period of extreme stress, I went for a month only sleeping 3 hours a night, and my body finally collapsed from the strain. It scared me. I'm in the U.S., and a friend here told me about Anna and the Zeez Sleep Pebble. My friend let me borrow hers for a trial run, and it helped a bit the first week. I slept for 6-7 hours a few times, and even when I woke up during the night, I either got back to sleep or just didn't feel as bad the next day. I tried it for a few weeks with some mixed results and then tried sleeping without it for a few weeks for comparison. I was also trying some different supplements at the time, so I wasn't sure what was actually helping. But when my sleep started to get worse again, I ordered my own Sleep Pebble. I got the one for low resting heart rate. The first few nights with it, my sleep was really choppy, but I reached out to Anna and followed her suggestions, tried taking more Vitamin D, and it's been working!!! I feel like a human being again and often sleep 7-8 hours/night now. I occasionally still have a rough night of sleep if my day was especially stressful or after a bout of illness. But it seems to reset in a few days with the Sleep Pebble, and my baseline is now GOOD sleep for a solid 6 hours at least. I'm so, so grateful. It honestly feels like it's given me my life back.
