5 Fuggin Stars – Life-changing. I finally slept.
I don't even know how to put this into words. I've struggled with severe sleep issues for years—both falling and staying asleep. I've tried everything: melatonin, Benadryl, Dramamine, even prescriptions like Xanax and Ativan. Nothing ever gave me more than a few broken hours… until now. I took the full 1,000mg serving of Double Wood glycine (two 500mg pills), and for the first time in years, I slept from 10:30 PM to 4:00 AM without waking up once. No grogginess, no melatonin nightmares, no side effects—just deep, peaceful, real sleep. I honestly got emotional. It's been so long since my body felt safe enough to truly rest. I have POTS, which makes my heart race and makes it extremely hard for me to relax enough to sleep. I'm also hard to sedate—most medications barely touch me, even at high doses. For glycine to calm my nervous system enough for that kind of sleep… it's honestly unbelievable. If you're struggling with sleep, especially if you're neurodivergent, sensitive, or dealing with a condition like POTS that keeps your body in overdrive—please try this. I've been so desperate for so long, and this has given me hope. It might just help you too. It's truly changed my life.
